    The clinical results of photodynamic therapy of maxillary sinusitis have been presented. 0.1%-Methylene Blue aqueous solution in combination with He-Ne laser irradiation (632.8 nm) has been used for treatment of patients with acute and chronic maxillary sinusitis. Efficacy of the photodynamic therapy was estimated with the use of the following criteria: the state of respiration, olfaction, duration of purulent discharge, reconstruction of transport function of ciliary epithelium, etc. The obtained results have shown that the photodynamic therapy is effective in comparison with conservative methods of treatment of the diseases.

  3. MRI of maxillary sinuses

    A mucous membrane of the maxillary sinus is clinically important in the dental fields. Magnetic resonance imaging (MRI) can demonstrate a mucous membrane because the mucosa contains rich free water. However, the morphology and location of the mucous membrane of normal maxillary sinuses have not been studied well by MRI. T2-weighted coronal images were obtained by spin echo technique in 40 normal volunteers. The eight maxillary sinuses were classified into four groups (Type 1∼IV) according to the morphology and also classified into five groups (Type a, b1, b2, b3, c) according to the location of the mucous membrane. Coronal images obtained at a standard angle of 77 degree to the Frankfort horizontal (FH) plane was the best for the evaluation of maxillary sinus because the image displayed the maximum cross-section of the maxillary sinus. In the normal cases, Type I (no high signal intensity) was observed in 20 sites, Type II (linear high signal intensity) in 48 sites, Type III (belt-like high signal intensity) in 11 sites and Type IV (mass-like high signal intensity) in 1 site. Type a (medial∼basal wall) was observed in 46 sites, Type b1 (medial wall alone) in 4 sites, Type b2 (basal wall alone) in 8 sites and Type c (entire wall) in 2 sites. Half of the cases showed the same findings bilaterally. Thus, MRI could demonstrate the morphology and location of the mucous membrane in the normal maxillary sinus so clearly that MRI was considered to be a useful diagnostic tool in the dento-maxillo-facial region.

    Schwannoma, also known as neurilemmoma, is a solitary, encapsulated peripheral tumour of neuroectodermal derivation that originates from schwann cells of neural sheath of motor/ sensory peripheral nerves or sympathetic nerves. About one- third of all schwannomas occur in head and neck region but nose and paranasal sinuses, are rare sites. We report a case of schwannoma arising from the maxillary sinus and eroding the orbital floor. To the best of our knowledge, this is the sixth; case of schw...

    Abstract Background We report a rare case of fatty tissue within the maxillary sinus in a 21-years-old woman, with a history of several previous punctures of the maxillary sinus. Case presentation Clinical data of the patient was analysed retrospectively. The patient presented with symptoms of left-sided chronic maxillary sinusitis and had undergone several punctures of the left maxillary sinus 18 months earlier. Subsequent to one of the procedures an acute pain in the left orbit lasting a co...

  6. Maxillary sinus carcinoma

    Primary site control, anatomical site of failure, survival, and complications of treatment were determined in a retrospective review of primary maxillary sinus carcinoma. Sixty-one patients were treated by radiation followed by surgery and 35 by radiation alone. Primary tumor control was achieved in 69% of patients receiving combined treatment, 14% of patients treated with radiation alone, and 49% of all patients. Local control did not differ with histological type. Virtually all epidermoid and undifferentiated carcinoma recurrences occurred within 2 years, but 27% of adenocarcinomas recurred after 2 years

  7. The development of maxillary sinus in children

    Developmental pattern of the maxillary sinuses was determined roentgenographically on Waters' view of 791 children ranged 11 months to 15 years of age. The width of maxillary sinuses increased according as age, the maximum width was measured in 14 ∼ 15 years. The maxillary sinuses developed inferolaterally, and the significant correlation was recognized between the width of maxillary sinuses, and neurocalvarium and facial bone. The incidence of opacity of maxillary sinuses were 50 % or more in children below 8 years of age, this means that opaque sinus are not necessarily abnormal. No significant correlation was recognized between the pattern of pneumatization and the size of the maxillary sinuses. (author)

    2011-01-01

    Ectopic eruption of teeth into a region other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin and maxillary sinus. Occasionally, a tooth may erupt in the maxillary sinus and present with local sinonasal symptoms attributed to chronic sinusitis. We present a case of an ectopic maxillary third molar tooth that caused chronic purulent sinusitis in relation to the right maxillary sinus.

  9. Maxillary Sinus mucormycosis mimicking sinus malignancy

    Mucormycosis is an opportunistic fulminant fungal infection in diabetic and immunocompromised patients. The infection is acquired in the nose and paranasal sinuses by the inhalation of the fungal spores. We report of a case of maxillary sinus mucormycosis in a 32-years-old non diabetic woman. She had right side facial pain, headache, unilateral right side nasal obstruction, and post nasal discharge (PND) for five years. Nasal endoscopy revealed pus and granulation tissue, and semi-black middle turbinate in right side nasal cavity. Computed tomography showed bone erosion and a large soft tissue mass similar to sinus carcinoma in maxillary sinus with extension into the ethmoidal sinus. She underwent functional Endoscopic sinus surgery. Macroscopically, the specimen consisted of multiple tissue fragment 0.8-1 cm. Microscopic findings included an inflammatory cells and deposited fungal elements (mucormycosis). So in the paranasal sinus and nasal cavity mass, mucormycosis should be included in the differential diagnosis, especially in the non diabetic and young patients. (author)

  10. Maxillary sinus textiloma: a case report

    2010-01-01

    Introduction Textilomas have been reported in many locations. We report the first case of textiloma located in the maxillary sinus that mimicked a sinus cyst recurrence on computed tomography images. Case presentation A 60-year-old Caucasian man was referred for persistent infection of the right maxillary sinus. A maxillary sinus benign cyst had been removed three months before. Computed tomography showed a sinus opacity evoking a cyst recurrence. A new operation was planned to remove the cys...

  11. Pneumatisation of the maxillary sinus in normal and symptomatic children

    The pattern of pneumatisation and normal width of the maxillary sinus in 191 Nigerian infants and children whose age range was 6 months to 14 years was determined. Fifty-four percent of children with no respiratory tract or sinus infection had opaque maxillary sinus. A figure of 44.5% was obtained amongst children with suspected bronchopneumonia. Only 41.5% of suspected cases of sinusitis, acute and chronic middle ear disease had opaque sinus. The highest rate of sinus opacity was seen in children under 2 years who were asymptomatic. The mean maximal width of normally aerated sinus was 8.74 mm for children under 2 years, 16.5 mm for 3-6 years, 21.5 mm for 7-11 years and 25 mm for children 12 years and above. We conclude that maxillary sinus opacity in our experience is an unreliable index for the diagnosis of sinusitis in children. (orig.)

    Full Text Available Background: Individual identification is a subtle concept and often one of the most important priorities in mass disasters, road accidents, air crashes, fires, and even in the investigation of criminal cases. Matching specific features detected on the cadaver with data recorded during the life of an individual is an important aspect in forensics, and can be performed by fingerprint analysis, deoxyribonucleic acid matching, anthropological methods, radiological methods and other techniques which can facilitate age and sex identification. Sinus radiography is one such method that has been used for determination of the sex of an individual. Hence, an attempt is being made to use the different dimensions of the maxillary sinus in the determination of sex using coronal and axial sections of plain computed tomography (CT scan. Materials and Methods: A total of 30 patients including 17 male and 13 female, visiting the Outpatient Department of the Mamata General Hospital were included as the study subjects. The dimensions of right and left maxillary sinuses of 30 subjects from plain CT were measured using SYNGO software and statistical analysis was done. Results: Sex determination using height, length, width, and volume of the maxillary sinus on both sides showed statistically significant results with a higher percentage of sexual dimorphism in the case of volume. Conclusion: Volume of the right maxillary sinus can be used as accurate diagnostic parameter for sex determination.

    2007-01-01

    Full Text Available Background. Mucocoele is histopathologically benign, cystic change of paranasal sinuses filled with mucoid contents, which with its growth is pressuring and destroying local bone walls. In only 3% of the cases it can be localized in maxillary sinuses. Etiology is unknown. Pyocoele develops by secondary infection. Case report. The male patient was 21 years old. His symptoms were runny nose with thick contents and heavy breathing on the right side of the nose, headaches, as well as the swelling of the right cheek. During clinical examination, the expansive change was found. It was completely closing the right side of the nose cavity. Computerized tomography (CT of paranasal cavities showed excessive expansion of the right maxillary sinus, with very thinned walls, while the cavity was filled with liquid. After antibiotics therapy, the radical operation of the right maxillary sinus was performed, based on Caldwell Luc method. The frontal wall was found to be extremely convex and thinned, while the medial wall was with dehiscention. The cystic change was extirpated. Mucocoele was proved by pathohistologic findings. Its wall was about 2 mm thick and it showed squamous metaplasia in the large part of the mucocoela epithel. In the submucosa fibrosis and inflammatory infiltrate was present. Postoperative follow-up was under control. Clinically and radiographycaly, six months after therapy, the patient does not have troubles. Conclusion. The rare localization of the mucocoeles in maxillary sinus can be explained with the width of the maxillary ostia. Infected mucocoeles, expanded to the local anatomical structures, should be operated on with classic radical surgical operation. .

    Aspergilloma of the paranasal sinus is a non-invasive form of aspergillosis, most often in the maxillary sinus. This case presents an 86-year-old female with aspergilloma of the left maxillary sinus. The patient's chief complaint was intermittent pain on the left maxillary first premolar area. A radiopacification of the left maxillary sinus was observed on the panoramic radiograph. Cone-beam computed tomography revealed complete radiopacification of the left maxillary sinus and scattered multiple radiopaque mass inside the lesion. Biopsy was performed under local anesthesia. On microscopic examination, numerous fungal hyphae, which branch at acute angle, were observed. The diagnosis was made as an aspergilloma based on the histopathologic examination.

  16. Post irradiation maxillary sinus sarcoma

    Radiation-induced cancer of the head and neck is well known, but radiation-induced sarcoma is rare. Only nine cases have been reported in the Japanese literature. We treated a patient with post irradiation sarcoma arising in the maxillary sinus. She is now 60 years old and had received radiation therapy for left maxillary carcinoma in 1952. In 1972, left maxillary sarcoma was found and she received postoperative radiation therapy again. Then right nasal carcinoma was found in 1980, and she again received postoperative radiation therapy. Then left maxillary sarcoma was found in 1992. There have been no previous reports of three consecutive radiation-induced malignancies developing in a patient. (author)

    Background: Metronomic chemotherapy consisting of methotrexate and celecoxib recently has shown promising results in multiple studies in head and neck cancers. However, these studies have not included patients with maxillary sinus primaries. Hence, the role of palliative metronomic chemotherapy in patients with maxillary sinus carcinoma that is not amenable to radical therapy is unknown. Methods: This was a retrospective analysis of carcinoma maxillary sinus patients who received palliative m...

  18. [The influence of local and combined acute suppurative Highmore maxillary sinusitis on the serum lactoferrin and interleukin-8 levels in the children].

    Klimova, I I; Zorina, V N; Zorina, R M; Akhtiamov, D R; Zorin, N A

    2014-01-01

    The objective of the present study was to estimate the influence of isolated and combined acute suppurative Highmore maxillary sinusitis on the serum lactoferrin (LF) and interleukin-8 (IL-8) levels in the children. A total of 70 children at the age varying from 4 to 15 years were available for the examination. Twenty of them constituted the control group, 29 presented with acute suppurative Highmore maxillary sinusitis, in 21 cildren this condition was combined with frontitis, ethmoiditis, otitis, and adenoiditis. Serum lactoferrin and interleukin-8 levels were measured by solid phase enzyme-linked immunoassay. It was shown that all the aforementioned forms of rhinosinusitis were associated with a significant increase of the serum LF level, an universal factor inactivating the propagation of bacterial, viral, and fungal pathogens. The level of IL-8 known to activate chemotaxis was increased only in the children presenting with combined forms of suppurative Highmore maxillary sinusitis. It is concluded that this difference can be used for the purpose of dufferential diagnostics of different forms of suppurative maxillary sinusitis. PMID:25588485

  3. Orthopantomographic study of the maxillary sinus

    The author has observed the orthopantomograms of the maxillary sinus which were taken by special exposure method to study mesiodistal dimension, shape, symmetrical relationship, bony septum of the maxillary sinus and relationship between upper lst molar and the maxillary sinus, that were selected 56 cases of 23 to 27 years old male, who have good systemic conditions and no missing teeth on upper posterior molar in normal occlusion, and obtained following conclusions: 1. Mesiodistal dimensions of the maxillary sinus are shown as follows; The mean of left dimension is 50.94 ± 8.34 mm and of right dimension is 49.50 ± 9.87 mm. 2. To the shape of the maxillary sinus, V or U shape are 33 cases(29.5%) and W shape are 77 cases (70.5%). 3. In the ralationship between upper lst molar and floor of the maxllary sinus, superimposition are 62 cases (55.36%) a nd approach are 50 cases (44.64%). 4. In the right and left symmetrical relationship of the maxillary sinus, symmetry are 37 cases (66.07%) and asymmetry are 19 cases (33.93%). 5. The bony septums in the maxillary sinuses revealed that presence of bony septums are 29 cases (25.8%) and absence ar e 83 cases (74.11%).

    2015-06-01

    To facilitate safe placement of orthodontic anchor screws (miniscrews), we investigated the frequency of maxillary sinus perforation after screw placement and the effect of sinus perforation on screw stability. Maxillary sinus perforations involving 82 miniscrews (diameter, 1.6 mm; length, 8 mm) were evaluated using cone-beam computed tomography. All miniscrews were placed in maxillary alveolar bone between the second premolar and first molar for anchorage for anterior retraction in patients undergoing first premolar extraction. The placement torque and screw mobility of each implant were determined using a torque tester and a Periotest device, and variability in these values in relation to sinus perforation was evaluated. Eight of the 82 miniscrews perforated the maxillary sinus. There was no case of sinusitis in patients with miniscrew perforation and no significant difference in screw mobility or placement torque between perforating and non-perforating miniscrews. The sinus floor was significantly thinner in perforated cases than in non-perforated cases. A sinus floor thickness of 6.0 mm or more is recommended in order to avoid miniscrew perforation of the maxillary sinus. PMID:26062857

  5. Maxillary sinus manifestations of methamphetamine abuse.

    Faucett, Erynne A; Marsh, Katherine M; Farshad, Kayven; Erman, Audrey B; Chiu, Alexander G

    2015-01-01

    Methamphetamines are the second most commonly used illicit drug worldwide and cost the United States health-care system ∼$23.4 billion annually. Use of this drug affects multiple organ systems and causes a variety of clinical manifestations. Although there are commonly known sequelae of methamphetamine abuse such as "meth mouth," there is limited evidence regarding maxillary sinus manifestations. The following cases highlight the initial evaluation and management of two methamphetamine abusers with loculated purulent collections within the maxillary sinus as a result of methamphetamine abuse. Our aim was to delineate the otolaryngologic symptoms associated with the patients' methamphetamine abuse. Computed tomography and magnetic resonance imaging studies revealed loculated purulent collections within the maxillary sinus of probable odontogenic origin in both patients. Methamphetamine abuse leading to rampant caries and poor oral hygiene may predispose individuals for craniofacial infections and fluid collections. These cases illustrate the development of maxillary sinusitis and maxilla mucoceles that have been associated with methamphetamine use. PMID:25675268

    Periorbital soft tissue swelling may result due to primary orbital pathology or from adjacent facio-maxillary or sino-nasal inflammatory causes. Osteomyelitis of maxilla in the pediatric age group is a rare entity in this era of antibiotics. We present an 11-month-old female infant who was brought with peri-orbital selling and purulent nasal discharge. Computed Tomography showed erosions of the walls of maxillary sinus suggestive of osteomyelitis. Culture of sinus scraping showed Staphylococc...

  7. Development of maxillary sinuses in childhood

    The purpose of this study was to clarify the development of the maxillary sinuses in childhood. Between June 1983 and December 1985, a total of 120 children under 15 years old were enrolled in this study. Cranial X-ray CT scans were performed using a GE CT/T 8800 and slice thickness were 1.5 mm under 2 years old and 5.0 mm for age above 3 years. Forty-five patients who had facial anomalies, or growth retardation, or premature infants were excluded from further analysis. The remaining 75 patients were evaluated for the development of the maxillary sinuses. The scans were made in the coronal and saggital planes. Anterior-posterior diameter (length) and mid-lateral diameter (width), and volume of the maxillary sinuses were measured by using the image processing system that was developed by us. Cranio-caudal diameter (height) was calculated by multiplying the slice thickness by the total number of the slices taken from the area of the maxillary sinus. Three dimensional structures of the maxillary sinuses were also displayed using the same system. The sizes of maxillary sinuses in the new born were 7.3 ± 1.9 mm(mean ± S.D.) in length, 6.7 ± 1.6 mmin height, and 5.2 ± 1.3 mm in width. These results were similar to those reported by others. The sizes of the maxillary sinuses were increased rapidly by the age 3 - 4 years. The numerical values for theses three measurements were greater than those previously reported, especially for height. The levels of upper borders of these maxillary sinuses in infants and young children were higher than those of inferior rimbs of the orbits. The results for the three dimensional displays and volume measurements performed on 66 children above 1 year old are also presented. (author)

  8. Maxillary sinus atelectasis report of two cases

    2002-08-01

    Full Text Available Maxillary sinus atelectasis is a rare and relatively unknown disease. Most patients present with non-sinonasel complaints. Negative intracavitary pressure due to ostial obstruction is suggested as the most probable etiology. Two patients with sinus atelectasis are presented in this paper: Case 1 presented with enophthalmus and maxillary sinus opacity and atelectasis in imaging. Endoscopic uncinectomy and midle antrostomy was done for this patient. Case 2 presented with mid-facial deformity and depression. Caldwel-Luc procedure with inferior meatal antrostomy was done. In 1 year follow up, they were asymptomatic and with no deterioration of facial deformity.

    Mena-Domínguez EA, Torres-Morientes LM, Tavárez-Rodríguez JJ, Bauer M, Martín-Pascual MC, Morais-Pérez D

    2013-10-01

    Full Text Available Introduction: The pneumocele is a pathological expansion of paranasal sinus containing only air, which can move the nearby structures. Radiologically is a hiperneumatizacion and elongation of paranasal sinus, that can be associated with bone loss. Description: Patient with facial fullness and pains on right side, occasionally nasal blockage that worsen with pressure changes, at exploration presents protrusion of maxillary mucosa into the nostril. Discussion: Pneumoceles can occur in any paranasal sinus. Usually remain asymptomatic and they are not diagnosed until it takes place an external deformity or displacement of neighbouring structures to the sinus, causing symptoms. Conclusion: The maxillary sinus neumoceles are a rare differential diagnosis of mucocele, tumors and trigeminal neuralgia. Surgery is curative, preferring an endoscopic approach.

  11. Treatment outcome of maxillary sinus cancer

    Jin-Hyoung Kang

    2009-12-01

    Full Text Available The standard treatment in the early stage of maxillary sinus cancer is surgical resection followed by postoperative radiation therapy. However, for locally advanced maxillary sinus cancer, a multimodality treatment approach is strongly recommended to improve the survival rate and quality of life of the patient. We determined the treatment outcomes of induction chemotherapy, concurrent chemoradiation therapy, and surgical resection for locally advanced maxillary sinus cancer. Forty-four patients with locally advanced maxillary sinus cancer, who had been treated between January 1990 and April 2008 at Kangnam St. Mary's Hospital, were retrospectively analyzed. The objective response rates were 70%, 53%, and 57% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and concurrent chemoradiation therapy groups, respectively. The orbital preservation rates were 83%, 100%, and 75% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and surgical resection groups, respectively. In seven of nine patients in whom the orbit could be preserved after induction chemotherapy, the primary tumors were removed completely. However, although the orbits were preserved in three patients who underwent surgical resection as a primary treatment, all three cases were confirmed to be incomplete resections. We found that active induction chemotherapy for locally advanced cancer of the maxillary sinus increased the possibility of complete resection with orbital preservation as well as tumor down-staging.

  12. A case report of mucoid retention cyst in maxillary sinus

    The author have observed mucoid retention cyst in the right maxillary sinus of the patient, 41 year old woman, complained discharging of purulent exudate on the right maxillary molar area, and obtained the following conclusions; 1. The mucoid retention cyst in maxillary sinus casts a faint dome shaped shadow into the radiolucent image of maxillary sinus. 2. The mucoid retention cyst in maxillary sinus may occurred without the history of trauma. 3. Intraoral standard films are also valuable for the interpretation of the lesions in maxillary sinus but only extraoral roentgenograms.

  14. Maxillary sinus disease of odontogenic origin.

    Mehra, Pushkar; Murad, Haitham

    2004-04-01

    Odontogenic sinusitis is a well-recognized condition and accounts for approximately 10% to 12% of cases of maxillary sinusitis. An odontogenic source should be considered in patients with symptoms of maxillary sinusitis who give a history positive for odontogenic infection or dentoalveolar surgery or who are resistant to standard sinusitis therapy. Diagnosis usually requires a thorough dental and clinical evaluation with appropriate radiographs. Common causes of odontogenic sinusitis include dental abscesses and periodontal disease perforating the Schneidarian membrane, sinus perforations during tooth extraction, or irritation and secondary infection caused by intra-antral foreign bodies. The typical odontogenic infection is now considered to be a mixed aerobic-anaerobic infection, with the latter outnumbering the aerobic species involved. Most common organisms include anaerobic streptococci, Bacteroides, Proteus, and Coliform bacilli. Typical treatment of atraumatic odontogenic sinusitis is a 3- to 4- week trial of antibiotic therapy with adequate oral and sinus flora coverage. When indicated, surgical removal of the offending odontogenic foreign body (primary or delayed) or treatment of the odontogenic pathologic conditions combined with medical therapy is usually sufficient to cause resolution of symptoms. If an oroantral communication is suspected, prompt surgical management is recommended to reduce the likelihood of causing chronic sinus disease. PMID:15064067

  15. Volumetric measurement of the maxillary sinus by coronal CT scan

    The volume of the maxillary sinus was estimated by coronal CT scan. The purpose of this study was to compare the estimated volume of the normal maxillary sinus with that of the inflamed maxillary sinus. Patients were classified following evaluation by CT scan of the paranasal sinuses into 3 categories. Group A (n=12): Patients suffered from headache, facial pain and epistaxis, but CT scans of their nasal cavity and paranasal sinus were within normal limits without inflammatory change. Group B (n=69): Patients with bilateral chronic maxillary sinusitis, CT scans of whom showed inflammatory changes in both maxillary sinuses. All of the patients in this group underwent sinus surgery after coronal CT scans. Group C (n=14): Patients with unilateral chronic maxillary sinusitis, CT scans of whom showed inflammatory change in unilateral maxillary sinuses. CT scans of these patients were measured by Plannimeter to take the area of each image of the maxillary sinus. Consecutively imaged areas were summated by integral calculus to obtain an estimate of the sinus volume. The mean maxillary sinus volume in the affected sinuses was significantly smaller than those in the contralateral normal sinuses (p<0.05, Wilcoxon-test). The various volumes of the maxillary sinuses and the developmental cause were discussed. Comparison of groups A with B suggested three distinct patterns; the maxillary sinus volume has decreased due to inflammatory changes in the bone. The small sinuses have a tendency to develop chronic inflammatory change. The aeration in the maxillary sinus may be decreased when anatomic variations that may obstruct the ethmoid infundibulum exist. (K.H.)

    Full Text Available Background: Metronomic chemotherapy consisting of methotrexate and celecoxib recently has shown promising results in multiple studies in head and neck cancers. However, these studies have not included patients with maxillary sinus primaries. Hence, the role of palliative metronomic chemotherapy in patients with maxillary sinus carcinoma that is not amenable to radical therapy is unknown. Methods: This was a retrospective analysis of carcinoma maxillary sinus patients who received palliative metronomic chemotherapy between August 2011 and August 2014. The demographic details, symptomatology, previous treatment details, indication for palliative chemotherapy, response to therapy, and overall survival (OS details were extracted. SPSS version 16 was used for analysis. Descriptive statistics have been performed. Survival analysis was done by Kaplan-Meier method. Results: Five patients had received metronomic chemotherapy. The median age was 60 years (range 37-64 years. The proportion of patients surviving at 6 months, 12 months, and 18 months were 40%, 40%, and 20%, respectively. The estimated median OS was 126 days (95% confidence interval 0-299.9 days. The estimated median survival in patients with an event-free period after the last therapy of <6 months was 45 days, whereas it was 409 days in patients with an event-free period postlast therapy above 6 months (P = 0.063. Conclusion: Metronomic chemotherapy in carcinoma maxillary sinus holds promise. It has activity similar to that seen in head and neck cancers and needs to be evaluated further in a larger cohort of patients.

  17. Radiologic study of the maxillary sinusitis

    Radiographic features of maxillary sinusitis, type of mucosal thickening, types of bony wall change, and relationship between the radiographic features and symptoms of patients were observed and classified in the Waters' view of 360 patients with 441 maxillary sinuses demonstrating radiologic change was observed in the 154 periapical films. Finally, the value of orthopantomography in the diagnosis of maxillary sinusitis was evaluated in the 138 cases, The obtained results were as followings. 1. Among 441 maxillary sinuses examine by Waters' projection, mucosal thickening was seen in 56.7% and generalized opacification was seen in 36.3%. 2. Among 270 mucosal thickenings classified 8 types, overall regularly thickened type cortical plates was the highest in incidence (36.3%). 3. Bony wall change was seen in 35.6% of all cases and the indistinct while line of the cortical plates was the highest in incidence (78.2%) among the 6 types. 4. Pain (419%) and pus discharge (21.0%) were the most frequent symptoms. And pus discharge, foul odor, and headache was more prevalent in type of generalized opacification than any other types. 5. Regular pneumatization involving all roots of premolars and molars was the highest in incidence (55.0%). The first molar presented the most frequent involvement (61.0%). 6. In orthopantomography, 46.4% showed apparent increased radiopacity and 23.9% showed suspicious increased radiopacity in comparison to Water's projection.

    2016-02-01

    Full Text Available ABSTRACT INTRODUCTION: The proximity of the roots to the maxillary sinus can create a variety of risks. OBJECTIVE: To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies. METHODS: Three radiologists analyzed 109 cone beam computed tomography (CBCT images. The Kappa test was used to assess the intra- and inter-rater agreement. The chi-squared test and prevalence ratio were used to test the hypothesis that roots of healthy teeth in the maxillary sinus favored the occurrence of sinus pathologies ( p = 0.01. RESULTS: Intra- and inter-rater agreement ranged from good to excellent. The chi-squared test demonstrated a statistically significant difference ( p = 0.006 between the tooth roots in diseased maxillary sinuses (6.09% and those in normal sinuses (3.43%. The prevalence ratio test showed a statistically significant higher prevalence of tooth roots in diseased sinuses than in normal sinuses ( p < 0.0001. Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses. CONCLUSION: Dental roots in the maxillary sinus are almost twice as likely to be associated with diseased sinuses than normal sinuses. Healthy teeth whose roots are inside the maxillary sinus may induce an inflammatory response in the sinus membrane. It is suspected that dental procedures may exacerbate the condition.

  3. Pathologic changes in the maxillary sinus wall after conservative therapy in odontogenic maxillary sinusitis. Examination using bone scintigraphy

    Single photon emission computed tomographic bone scintigraphy (bone SPECT) was performed in 16 patients with odontogenic maxillary sinusitis to compare inflammatory changes in the maxillary sinus wall including the alveolar process (bony lesions) before and after conservative therapy. Morphologic changes in bony lesions as evaluated by bone SPECT images correlated with those of the maxillary sinus mucosa (mucosal lesions) as evaluated by CT images. Morphologic changes in the bony lesions also correlated with changes in inflammatory activity in the maxillary alveolar process as functionally evaluated by bone SPECT before and after conservative therapy. Odontogenic maxillary sinusitis is considered a disease in which maxillary alveolitis causes mucosal lesions as well as bony lesions. Changes in alveolitis are associated with morphologic changes in bony lesions after conservative therapy, and these changes affect the pathophysiologic nature of odontogenic maxillary sinusitis. Bone SPECT is valuable for predicting outcome and treatment planning in patients with odontogenic maxillary sinusitis. (author)

  4. A case report of antrolith in the maxillary sinus

    The antrolith is a rare disease in the maxillary sinus. We experienced a 67-year-old female whose chief complaint was an intermittent dull pain of clinical, radiological and histological findings, we diagnosed it as antrolith in the left maxillary sinus and obtained results as follows: 1. Three radiopaque substances in the left maxillary sinus were revealed as 'Antroliths'. 2. These antroliths were movable in the left maxillary antrum and combined with maxillary sinusitis. 3. We supposed it internal origin of nidus in this case.

    Background Proximity of the dental roots to the sinus floor makes dental disease a probable cause of maxillary sinusitis. The aim of this study was to find out if maxillary sinus pathologic changes were more prevalent in patients with dental disease and to evaluate the performance of computed tomography (CT) in analyzing and detecting apical periodontitis and other odontogenic causes on the maxillary sinusitis etiology in a Portuguese Caucasian population. Material and Methods Retrospective cohort study. The total sample of 504 patients and their CT was included in this study. The patients were from a private dental clinic, specializing in oral surgery, where the first complaint was not directly related to sinus disease, but with dental pathology. For each patient, the etiological factors of maxillary sinusitis and the imaging CT findings were analyzed. All the axial, coronal and sagittal CT slices were evaluated and general data were registered. The latter was selected based on the maxillary sinus CT published literature. Results 32.40% of patients presented normal sinus (without any etiological factor associated), 29.00% showed presence of etiological and imaging findings in the maxillary sinus, 20.60% had only imaging changes in the maxillary sinus and 18.00% of patients presented only etiological factors and no change in the maxillary sinus. Conclusions Radiological imaging is an important tool for establishing the diagnosis of maxillary sinus pathology. These results indicate that the CT scan should be an excellent tool for complement the odontogenic sinusitis diagnosis.

  6. Infantile maxillary sinus osteomyelitis mimicking orbital cellulitis

    Nagarajan Krishnan

    2014-01-01

    Full Text Available Periorbital soft tissue swelling may result due to primary orbital pathology or from adjacent facio-maxillary or sino-nasal inflammatory causes. Osteomyelitis of maxilla in the pediatric age group is a rare entity in this era of antibiotics. We present an 11-month-old female infant who was brought with peri-orbital selling and purulent nasal discharge. Computed Tomography showed erosions of the walls of maxillary sinus suggestive of osteomyelitis. Culture of sinus scraping showed Staphylococcus aureus growth and the child improved with intravenous cloxacillin therapy. This case is presented due to the rarity of its presentation in this age group and for awareness to consider this entity in children having fever and peri-orbital swelling.

  8. Aggressive fibrous dysplasia of the maxillary sinus

    Five of 34 patients (ages 4-21 years), who were subsequently diagnosed histologically as having fibrous dysplasia of the maxillary sinus, rapidly developed soft tissue masses of the malar region over a period of less than 4 months with accompanying pain (2 patients) and nasal obstruction and exophthalmos (2 patients). Each was clinically suspected of having a sarcoma. After resection, all lesions developed regrowth. At histopathologic examination, both initial and recurrent masses proved to be typical fibrous dysplasia. (orig./UWA)

  9. Prognostic factors of maxillary sinus epithelial carcinoma

    Objective: To evaluate the relation between clinicopathological character- isties and prognosis in maxillary sinus epithelial carcinoma (ECMS). Methods: 124 such patients were reviewed retrospectively. There were treated by radiotherapy alone (RT-, 40 patients), surgery alone(S-, 18 patients)and combined modality therapy (R+ S-, 66 patients). Kaplan-Meier method was used to analyze the survival, Logrank test was used to compared the difference between groups. Multivariate analysis was performed by Cox proportional hazard model. Results: The overall 5-year survival, cancer-specific survival and progression-free survival rates were 32.5%, 37.4% and 27.2%, respectively. Univariate analysis showed that tumor location, histological type, T stage, N stage, clinical stage and treatment modality were associated with cancer-specific survival and progression-free sur- vival, while age was only associated with cancer-specific survival. Multivariate analysis indicated that histological type, T stage, clinical stage and treatment modality were independent prognostic factors. Conclusions: T stage and clinical stage are the independent prognostic factors for maxillary sinus epithelial carcinoma. Prophylactic neck irradiation is necessary even for T3-T4N0 patients. The best treatment strategy for maxillary sinus carcinoma needs further research. (authors)

  11. Maxillary sinus pneumatization after maxillary molar extraction assessed with cone beam computed tomography

    The purpose of this study was to examine the inferior expansion of the maxillary sinus floor following maxillary molar extraction. Cone beam computed tomographic images of 59 subjects were used to evaluate the height difference of the maxillary sinus floor between extraction sites and contralateral dentate sites. The height of the maxillary sinus floor was defined as the vertical distance to the Frankfort plane from the level of the anterior nasal spine to the most inferior point of the sinus floor. We examined the difference in sinus pneumatization according to the number of missing teeth and the vertical relationship of the molar roots to the sinus floor. The inferior expansion of the maxillary sinus floor was 1.20 ± 1.86 mm on the maxillary first molar and 1.90 ± 2.42 mm on the maxillary second molar. Increased expansion was observed in cases where two proximate molars were extracted. There was no significant difference in sinus pneumatization following extraction according to the vertical relationship of the molar roots to the sinus floor. The results of this study confirm that sinus pneumatization occurs following maxillary molar extraction. In situations where pneumatization can affect treatment after molar extraction, three-dimensional radiography should be considered.

  13. Maxillary sinusitis - a comparative study of different imaging diagnosis methods

    We conducted prospective study comparing different methods (plain X-rays, computed tomography and ultrasonography mode-A) for the initial diagnosis of maxillary sinusitis. Twenty patients (40 maxillary sinuses) with a clinical history suggestive of sinusitis included in this study. The results were classified as abnormal or normal, using computed tomography as gold standard. The sensitivity for ultrasonography and plain X-rays was 84.6% and 69.2%, respectively. The specificity of both methods was 92.6%. This study suggests that ultrasonography can be used as a good follow-up method for patients with maxillary. sinusitis. (author)

    2014-01-01

    We present an osteolytic nasal polyp of the maxillary sinus with clinical features and radiographic features mimicking that of a malignancy. Maxillary sinusitis being a common inflammatory condition progressed to cause destruction of the maxillary bone and spread into the facial soft tissue, which is quite a rare occurrence. We have discussed in detail the clinical, radiological, histopathology and management of this uncommon presentation of a common case.

  15. Maxillary sinus carcinoma: result of radiation therapy

    This hundred and sixteen patients with carcinoma of the maxillary sinus received primary therapy consisting of external beam irradiation alone or in combination with surgery and/or chemotherapy at the Department of Radiology, Tokyo Medical and Dental University Hospital, between 1953 and 1982. In our institution, methods of treating cancer of the maxillary sinus have been changed from time to time and showed different control rates and clinical courses. An actuarial 10-year survival rate of 21% has been obtained by the megavoltage irradiation alone as well as 34% actuarial 10-year survival rate by megavoltage irradiation with surgery. After the introduction of conservative surgery followed by conventional trimodal combination therapy, the local control rate has been improved. The amount of functional, cosmetic, and brain damages have been remarkably decreased by this mode of therapy. The actuarial five year survival rate was 67%. In addition, along with the improvement of the local control rate, the control of nodal and distant organ metastases have been emerging as one of the important contributions to the prognosis of this disease

  16. A clinical analysis of maxillary sinus cancer

    Thirty-two patients (23 males, 9 females) with maxillary sinus cancer were treated at Kyushu University Hospital during 2000-2008. They were classified by T classification as 5 cases with T2, 13 with T3, 12 with T4a, and 2 with T4b. Between 2000 and 2003, 16 patients were given irradiation, intra-arterial 5-fluorouracil (5-FU) infusion chemotherapy, maxillectomy and postoperative irradiation. After 2004, two patients with T4b maxillary sinus cancer were treated by superselective intra-arterial chemotherapy with Cisplatin (CDDP) and Docetaxel (DOC) and irradiation. Other patients were given irradiation and chemotherapy with S-1 and intra-arterial infusion of 5-FU. The 3-year survival rate was 68.3% for all patients. The 3-year survival rate was 74.6% for patients treated after 2004, whereas it was 62.5% for patients treated between 2000 and 2003. Chemotherapy with S-1 or superselective intra-arterial chemotherapy with CDDP and DOC improved cause-specific survival rates. (author)

  18. CT-MPR invaluable in diagnosing odontogenic maxillary sinusitis

    In everyday examination, it is usual to encounter odontogenic maxillary sinusitis patients. Odontogenic maxillary sinusitis is generally best diagnosed by dental X-ray imaging. Many medical facilities not having a dental X-ray unit use coronal computed tomography (CT) images to diagnose odontogenic maxillary sinusitis. Coronal CT imaging causes artifacts, however due to dental prosthesises. Computed tomography-Multiplanar reformation (CT-MPR) imaging has proved useful in evaluating the paranasal sinus because it is not influenced by dental prosthesises. We evaluated the usefulness of CT-MPR for diagnosing odontogenic maxillary sinusitis by retrospectively analyzing 16 patients, with the following results. We couldn't diagnose all cases of odontogenic maxillary sinusitis in posteroanterior and Waters projection images. Panoramic radiography is needed to diagnose odontogenic maxillary sinusitis. Dental X-ray imaging missed some cases, but all cases were diagnosed by CT-MPR imaging, giving a 100% diagnosestic rate. CT-MPR imaging is thus at least as valuable or better than dental X-ray imaging in diagnosing odontogenic maxillary sinusitis. (author)

  19. Radiation Therapy of Maxillary Sinus Cancer

    Purpose: Maxillary sinus cancers usually are locally advanced and involve the structures around sinus. It is uncommon for this cancer to spread to the regional lymphnodes. For this reason, local control is of paramount important for cure. A policy of combined treatment is generally accepted as the most effective means of enhancing cure rates. This paper reports our experience of a retrospective study of 31 patients treated with radiation therapy alone and combination therapy of surgery and radiation. Materials and Methods: Between July 1974 and January 1992, 47 patients with maxillary sinus cancers underwent either radiation therapy alone or combination therapy of surgery and radiation. Of these, only 31 patients were eligible for analysis. The distribution of clinical stage by the AJCC system was 26%(8/31) for T2 and 74%(23/31) for T3 and T4. Eight patients had palpable lymphadenopathy at diagnosis. Primary site was treated by Cobalt-60 radiation therapy using through a 45 .deg. wedge-pair technique. Elective neck irradiation was not routinely given. Of these 8 patients, the six who had clinically involved nodes were treated with definite radiation therapy. The other two patients had received radical neck dissection. The twenty-two patients were treated with radiation alone and 9 patients were treated with combination radiation therapy. The RT alone patients with RT dose less than 60 Gy were 9 and those above 60 Gy were 13. Results: The overall 5 year survival rate was 23.8%. The 5 year survival rate by T-stage was 60.5% and 7.9% for T2 and T3, 4 respectively. Statistical significance was found by T-stage (p30.1). The 5 year survival rate for RT alone and combination RT was 22.5% and 27.4%, respectively. The primary local control rate was 65%(20/31). Conclusion: This study did not show significant difference in survival between RT alone and combination RT. There is still much controversy with regard to which treatment is optimum. Improved RT technique and

  20. Positional relationship between the maxillary sinus floor and the apex of the maxillary first molar using cone beam computed tomograph

    To assess the positional relationship between the maxillary sinus floor and the apex of the maxillary first molar using cone beam computed tomograph (CBCT). CBCTs from 127 subjects were analysed. A total of 134 maxillary first molars were classified according to their vertical and horizontal positional relationship to the maxillary sinus floor and measured according to the distance between the maxillary sinus floor and the maxillary first molar. Type III (The root projected laterally on the sinus cavity but its apex is outside the sinus boundaries) was dominated between 10 and 19 years and type I (The root apex was not in contact with the cortical borders of the sinus) was dominated (P<0.05) between 20 and 72 years on the vertical relationship between the maxillary sinus floor and the apex of the maxillary first molar. The maxillary sinus floor was located more at the apex (78.2%) than at the furcation (21.3%) for the palatal root. The distance from the root apex to the maxillary sinus floor confined to type I was increased according to the ages (P<0.05). Type M (The maxillary sinus floor was located between the buccal and the palatal root) was most common (72.4%) on the horizontal relationship between the maxillary sinus floor and the apex of the maxillary first molar. CBCT can provide highly qualified images for the maxillary sinus floor and the root apex of the maxillary first molar.

  1. Measurement of maxillary sinus volume using Computed Tomography

    To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. Fifty-two (95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm3, respectively. There was a significant sex difference in the sinus volume (p<0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides (p<0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume (p<0.0001). In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

  2. CT findings of fungal infection of maxillary sinuses

    In recent years, fungal infection of the paranasal sinuses has increased. However, the preoperative diagnosis is often difficult. We report four cases of fungal infection of the paranasal sinuses. Their CT scans. Showed: 1) A high density area in the homogeneous shadow. 2) A mass suspected of being a fungus ball surrounding the opening of the maxillary sinus to the nasal cavity. 3) Thickening of bone in the maxillary sinus except in the inner wall. These results indicate that CT scanning is useful in the diagnosis of fungal infection of the paranasal sinuses. (author)

  3. Giant complex odontoma in maxillary sinus.

    Carvalho Visioli, Adriano Rossini; de Oliveira E Silva, Cléverson; Marson, Fabiano Carlos; Takeshita, Wilton Mitsunari

    2015-01-01

    In this manuscript, we present a rare case report of giant complex odontoma in the maxillary sinus, where the applied therapy included complete excision of the lesion with a conservative approach. Odontomas are also called benign growth abnormalities or hamartomas. They represent a more common type of odontogenic tumor and are related to various disorders such as bad dental placements, expansion, increased volumetric bone, and no eruption of permanent teeth. Usually they have an asymptomatic evolutionary course. The etiologic factors, although obscure, are related to local trauma, infection, and genetic factor. The structural composition of an odontoma consists of mature dental tissues. Odontomas can be differentiated according to their anatomical presentations: Compound odontoma-clusters of several denticles and complex odontoma-well defined tumefaction mass. The diagnosis can be performed by radiographic examination. PMID:26389051

  4. Carcinoma of Maxillary Sinus. A case Presentation.

    Blas Jorge González Manso

    2007-08-01

    Full Text Available Tumors of the nasosinuous tract developed in the air cavities usually present a considerable growing before the patient feel any symptom or sign. Great part of the symptomatology is given due to the invasion of the tumor to neighbour structures such as oral and nasal cavities and orbits. A case of a 62 year-old male patient is presented after being under a dental extraction. A bucco-sinuous communication was diagnosed. It did not respond to different treatments and after some moths an epidermoid carcinoma of the right maxillary sinus appeared. It is of great interest to let this case been known in order to outstand the importance of an early diagnosis to get a better vital prognosis in this kinds of lesions.

  5. Epithelioid Hemangioendothelioma of the Maxillary Sinus.

    Avadhani, Vaidehi; Loftus, Patricia Anne; Meltzer, Daniel; Wang, Beverly; Tabaee, Abtin

    2016-06-01

    The clinical course and pathologic features of a 72 year old female who presented with epistaxis are presented. Radiographic findings were notable for a large, soft tissue lesion filling the maxillary sinus with significant bony erosion and expansion. The patient was ultimately diagnosed with epithelioid hemangioendothelioma (EHE) and underwent endoscopic resection. She has no evidence of local, regional or distant recurrence 14 months post-surgery. The rarity of this neoplasm, the unusual anatomic location and non-specific symptoms present diagnostic and management challenges. Epithelioid vascular tumors encompass a spectrum of benign and malignant tumors. EHE itself is thought to have an intermediate malignant behavior pattern, though cases with indolent behavior have been reported. Differentiation of EHE from other lesions has historically based on histopathology. Additionally, recent studies have described a recurrent genetic fusion WWTR1-CAMTA1 in EHE, involving t(1;3) (p36;q25). This represents the second reported case of EHE arising in a paranasal sinus. The histopathologic findings of this lesion are reviewed. PMID:25963905

  6. Preoperative radiotherapy of maxillary sinus cancer

    This study was to evaluate the effectiveness of preoperative radiotherapy in maxillary sinus cancer. A retrospective analysis was done for 42 patients with maxillary sinus cancer who were treated with radiation with or without surgery from April 1986 to September 1996. There were 27 male and 15 female patients. Patients' age ranged from 24 to 75 years (median 56 years). Stage distribution showed 2 in T2, 19 in T3, and 21 in T4 lesions. The histologic type was squamous cell carcinoma in 38, undifferentiated carcinoma in 1, transitional cell carcinoma in 1, and adenoid cystic carcinoma in 2 patients, All patients were treated with radiation initially with a dosage range of 50.4-70.2 Gy (median 70.2 Gy) before further evaluation of remnant disease. Eleven patients were given induction chemotherapy (2 cycles of 5-fluorouracil and cisplatin) concurrently with radiotherapy. Six to eight weeks after radiotherapy with or without chemotherapy, computerized tomography (CT) of paranasal sinus was taken to evaluate remnant disease. If the CT finding showed remnant disease, a Caldwell-Luc procedure was done to get the specimen of suspicious lesions. A radical maxillectomy was done if the specimen was proven to contain malignancy. In contrast periodic follow-up examination was done without any radical surgery if the tissue showed only granulation tissue. Follow-up period ranged from 3 to 92 months with a median 16 months. Nine (21.4%) patients showed complete response (CR) and 33 patients (78.6%) showed persistent disease (PER) to initial radiotherapy. Among the 9 CR patients, 7 patients had no evidence of disease (NED), 1 patient had local failure, and 1 patient had regional failure. Among 33 PER patients, salvage total maxillectomy was done in 10 patients, and the surgery was not feasible or refused in 23 patients.

    We evaluated the usefulness of conebeam x-ray CT in the diagnosis of odontogenic maxillary sinusitis in 21 patients. Among teeth causing odontogenic maxillary sinusitis, 95% had apical lesions after root canal treatment. Most root canals were filled with filling materials incompletely. Apical lesions in inappropriately treated teeth thus caused odontogenic maxillary sinusitis. Conebeam CT involves 3-dimensional isotropic voxel image date in up to 512 frames for transaxial, coronal, and sagittal planes, so resolution in imaging on the body axis was especially high. Multiplanar reconstruction and volume rendering images at any optional plane could be obtained without interpolation. The relationship between causative teeth and the maxillary sinus could be observed and measured, and odontogenic maxillary sinusitis accurately diagnosed. In addition to the accurate diagnosis of apical lesions, maxilla, and maxillary sinus, periodontal ligament space, lamina dura, pulp cavity, root canal, canal-treated root, apical periodontitis, alveolar ostitis, marginal periodontitis of causative teeth could be observed. Metal artifacts were minimized, making conebeam CT useful in the diagnosis of periodontal tissue and causative teeth, including root-canal-treated and crown-restored teeth. (author)

  8. Trimodal combination therapy for maxillary sinus carcinoma

    Purpose: This study was conducted to evaluate the effectiveness of trimodal combination therapy (radiotherapy, intra-arterial chemotherapy, antrotomy) for the treatment of primary maxillary sinus carcinoma. Methods and Materials: Between 1977 and 1996, 110 patients with maxillary squamous cell carcinoma were treated with trimodal combination therapy at Tokyo Medical and Dental University Hospital. All tumors were classified according to the 1997 UICC TNM staging system. Eighty percent of patients had T3 or T4 tumors. The T3 and T4 tumors were also classified into three groups according to their location, as visualized using computed tomography: the posterior-lateral (P) group, the medial (M) group, and the upper (U) group. Eight patients received additional radiotherapy, and 37 patients underwent a second surgical procedure, in addition to the trimodal combination therapy. Results: The 5-year cause-specific survival and local control rates were 71% and 65%, respectively. The 5-year local control rate was 80% for the T1+2 tumors, 64% for the T3 tumors, and 52% for the T4 tumors (p=0.06). Patients in the P+M group who received a 5-fluorouracil (5-FU) dosage of more than 3500 mg had a better 5-year local control rate than patients who received a 5-FU dosage of less than 3500 mg (p=0.01). No improvement in the local control rate after a second surgical procedure or additional irradiation treatment was observed in any of the groups. Conclusion: Trimodal combination therapy provides good local control, with the final outcome depending on the T stage of the tumor and the dosage of 5-FU

  9. Radiotherapy of malignant tumor of maxillary sinuses

    Sixty nine patients of malignant tumors of the maxillary sinuses were treated at the Yonsei Cancer Center from January 1970 to March 1978 by CO-60 teletherapy unit. We analyzed their clinical findings, histopathological findings, clinical staging, treatment and results. The results are as follows; 1. Male to female ratio was 3 : 1. The most prevalent age group was in fifth, sixth and seventh decades (82.6%). 2. Histologically, squamous cell carcinoma occurred most frequently which was 53 in 69 patients (76.8%). Lymphoma and adenoid cystic carcinoma were 3 patients (4.3%) respectively. 3. Maxillary swelling was most frequent clinical manifestation and can be seen in 50 out of 69 patients (72.5%). 4. Clinical staging according to TNM system proposed by Sisson can be done in 49 patients. Majority of patients were T-3 and T-4 and occupied 83.7% (41/49). According to Ohmgren's Line, tumor locating in infrastructure were 33 patients and in suprastructure 16 patients. 5. Among 69 patients, 59 patients were treated by radiation only, 5 patients were surgery plus radiation and 5 patients by chemotherapeutic infusion plus radiation. 6. In 31 patients who might be passed 5 years after treatment, follow up can be done in only 13 patients. 10 patients were treated by radiation only and 3 patients by surgery plus radiation. Presumed 5 year survival rate was 3/10 (30%) in patients with radiation only and 2/3 (66.7%) in patients with surgery plus radiation. Among 13 patients, 5 patients occurred infrastructure and 5 patients in suprastructure. Mean survival months of patient with infrastructure were 49 months and suprastructure were 31.8 months.

  10. Maxillary sinus carcinoma: Natural history and outcome

    To assess natural history, treatment outcome and pattern of relapse in patients with maxillary sinus carcinoma. A review was conducted of the medical records of all adult patients with maxillary sinus carcinoma, who were treated at King Faisal Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia, between January 1990 and December 1999. A total of 60 patients were identified for analysis, 36 men and 24 women; the median age was 58-years (range 23-95). Major presenting symptoms were facial swelling 55%, facial pain 50%, and nasal obstruction 43.4%, with a median duration of 5-months (range 1-24). Histology was quamous cell carcinoma in 71.7% and adenoid cystic in 16.7%. They were restaged according to American Joint Committee on Cancer classification 1997 as II, III and IV in 1, 10 and 49. Thirty patients received treatment with curative intent (surgery in 4 patients, radiotherapy in 2, and combined modality in 24), 6 patients refused treatment and 24 were treated palliatively. With a median follow up of 50-months (range 2-128) in surviving patients treated with a curative intent, 12/30 failed locally, 4/30 in the regional neck nodes and 2/30 had systemic relapse. The actuarial 5-year overall survival (OS), relapse free survival (RFS) and local control rate (LC) were 55%, 39% and 51%. Treatment modality was the only significant prognostic factor for outcome, with 5 year OS, RFS and LC of 72%, 49% and 61%, for combined modality using surgery followed by radiotherapy compared to 0% for single approach (p=0.0003, p=0.0052 and p=0.0098). This study indicates that the majority of our patients presented with advanced disease, resulting in poor outcome to conventional treatment modalities. Efforts should be directed to minimize the delay in diagnosis at the primary care level. Combined modality treatment should be offered to all patients with locally advanced disease. New approaches such as neoadjuvant or concurrent chemoradiotherapy with or without surgery need to

  11. Maxillary Antrolith: A Rare Cause of the Recurrent Sinusitis

    Vijendra Shenoy

    2013-01-01

    Full Text Available Introduction. An antrolith is a calcified mass within the maxillary sinus. The origin of the nidus of calcification may be extrinsic (foreign body in sinus or intrinsic (stagnant mucus and fungal ball. Most antroliths are small and asymptomatic. Larger ones may present as sinusitis with symptoms like pain and discharge. Case Report. We report a case of a 47-year-old lady who presented with heaviness on the left side of the face and loosening of the left 2nd molar tooth since two months. CT scan of the osteomeatal complex and paranasal sinuses showed an opacification of bilateral maxillary sinus and an amorphous area of bone density in the left maxillary sinus. Because of the size of the mass, benign neoplasms were considered in the differential diagnosis. During an endoscopic sinus surgery, it was found to be an antrolith, which was successfully managed by antrostomy and Caldwell-Luc Surgery. Discussion. Antrolith is a rare condition. Rhinoliths are known to invade into the maxillary antrum, but a localised lesion in the antrum is very unusual. A case of an isolated antrolith is presented for its rarity and for differential diagnosis of localised antral disease. Conclusion. Antrolith should be considered as differential diagnosis of unilateral radio-opaque paranasal sinus lesions.

    Sinusitis of dental origin is a relatively frequent entity, and odontomas are considered to be the most common odontogenic tumors of the oral cavity. Eruption and infection of odontomas are extremely rare. Here, we report an interesting case where odontoma was found in the wake of the maxillary sinusitis onset.

  13. The CT findings of maxillary sinusitis comparing with conventional radiography

    The CT findings of 42 patients with surgically verified benign lesions of the maxillary sinus were evaluated to demonstrate the value of CT. Comparison with conventional radiological methods was made. The opacification of the maxillary sinus lumen in Waters view shows the relationship in proportion to the soft tissue that occupies the sinus in CT finding. The thickening in the posterior wall of the maxillary antra may cause the opacification in Waters view. The Waters view can depict more significantly the maxillary soft tissue in CT finding than the Caldwell view and panoramic view. CT is of value in demonstration of fluid level, mucosal swelling, mucosal thickening and the thickening of the bony walls. (author)

    To evaluate the value of panoramic radiography in diagnosing maxillary sinus inflammation. A total of 214 maxillary sinuses from 114 panoramic radiographs were assessed in this study. Two independent experienced oral radiologists evaluated the images in random order for sinus inflammation. Using Cone beam CT images as the gold standard, the sensitivity and specificity of panoramic radiography were calculated, and inter- and intraobserver agreement for panoramic interpretation were obtained. The mean sensitivity and specificity of panoramic radiography were 81.0% and 85.6%, respectively. The weighted kappas for inter- and intraobserver agreement of panoramic radiography were 0.56 and 0.60, respectively. Panoramic radiography is a reasonably accurate method for diagnosing maxillary sinus inflammation and can be used for screening. However, additional examinations should be considered in patients with potentially significant pathology.

    Pneumatization of the maxillary sinus limits the quantity of alveolar bone available for implant placement and may result in a lack of primary stability and difficulty in achieving osseointegration. The purpose of this study was to retrospectively analyze a group of patients who had implants placed in the posterior maxilla, calculate the prevalence of sinus augmentation, and identify factors related to sinus augmentation. With institutional review board approval, dental records from a population of patients who had implants placed in the maxillary posterior region between January 2000 and December 2004 were used to create a database. Independent variables were classified as continuous (age of the patient at stage 1 implant surgery [S1], time between extraction and S1, time between extraction and sinus augmentation, and time between sinus augmentation and S1) and categorical (gender, implant failure, American Society of Anesthesiologists system classification, smoking, osteoporosis, residual crestal bone height, implant position, implant proximity, prostheses type, and implant diameter and length). The dependent variable was the incidence of a sinus augmentation procedure. Simple logistic regression was used to assess the influence of each factor on the presence of sinus augmentation (P rate of 93.2% over a mean follow-up period of 35.7 months. Of 502 implants, 272 (54.2%) were associated with a sinus augmentation procedure. Among variables, residual crestal bone height (P edentulism. Sinus augmentation was significantly associated with implant failure and wide implants. PMID:21651386

  19. CT evaluation of maxillary sinus aspergillosis: morphological patterns on CT

    In order to classify the involving patterns of maxillary sinus aspergillosis on CT that will be an important guidance for functional endoscopic sinus surgery (FESS) and to evaluate CT findings of each pattern. We reviewed CT findings of 37 cases of maxillary sinus aspergillosis which were confirmed pathologically. These were classified into three patterns according to the location: the maxillary pattern(I), the infundibular pattern(II), and combined pattern(III). All cases were correlated with FESS findings. We also evaluated CT density, presence of contrast enhancement and calcifications, and surrounding bony changes of each pattern. The combined pattern was most commonly seen in 24 of 37 cases (64.9%). The maxillary pattern was identified in 8 (21.6%), with 5 (13.5%) cases demonstrating the infundibular pattern. These patterns were consistent with FESS findings. Calcifications were seen in 28 cases (75.7%). 31 cases (83.3%) revealed hypodensity and 16 cases among them showed peripheral enhancement. Central high density with peripheral low density rim was shown in 25% (2/8) of the maxillary pattern and 12.5% (3/24) of combined pattern. Surrounding bony changes were noted mainly in infundibular pattern and combined pattern. Erosion of uncinate process showed all cases of both patterns. Erosion or elevation of ethmomaxillary plate was seen in 3 of 5 cases of infundibular pattern and all cases of the combined pattern. CT findings of maxillary sinus aspergillosis can be classified into 3 patterns according to their distribution. These classification could be helpful for planning FESS approach. Calcifications are the most characteristic findings of maxillary sinus aspergillosis whereas CT density or enhancement pattern do not contribute to diagnosis

    2010-06-15

    To investigate and compare the prevalence, size, and location of maxillary sinus septa on panoramic and cone beam computed tomography (CBCT) images.Two hundred patients who had taken both panoramic and CBCT images were included. The location of maxillary sinus septa on the panoramic radiographs were recorded and confirmed on the CBCT images. Also the size of septa was measured on the reformatted CBCT images. The prevalence of the patients who had maxillary sinus septa was 51.0% and they showed 179 septa totally. Among them 51.0% of the patients had one septum, 32.4% two septa, 13.7% three, and 2.9% four. The measured heights of the septa were 4.37 {+-} 2.87 mm, 3.51 {+-} 2.47 mm, and 3.04 {+-} 2.37 mm in the medial, middle, and lateral areas, respectively. It was revealed that 1.0% was located at canine region, 18.0% at first premolar, 25.0% at second premolar, 22.7% at first molar, 19.8% at second molar, and 14.0% at third molar region. Among 213 septa depicted by the panoramic radiographs, only 69.0% were confirmed at the CBCT images. Since various heights and courses of the septa can develop in all parts of the maxillary sinus, adequate assessment of the inner aspect of the maxillary sinus is essential to avoid complications during sinus augmentation procedures. CBCT scanning is the preferred radiographic method for detecting the presence of sinus septa.

    2016-01-01

    Inflammatory myofibroblastic tumor (IMT) in the maxillary sinus is a diagnostic challenge. As IMT has various names, it has various findings in magnetic resonance image. Although destructive pattern in computed tomography and hypermetabolism in PET CT suggest malignancy, it is debatable whether it is a tumor or inflammatory lesion. Treatment of IMT usually includes surgery. However, IMT can be dealt with medical treatment according to histologic type and localization. We report a rare case of IMT in the maxillary sinus which is controlled by medical therapy. PMID:27038822

  4. CT features in second cancers of the maxillary sinus

    Five patients with a second maxillary cancer (squamous cell carcinoma), which developed 6 to 17 years after initial treatment for the first cancer on the opposite side, were compared with 21 control cases with a primary cancer on the basis of computed tomography (CT) findings. Generally, the second cancer was found at an earlier stage. The specific CT findings of early sinus carcinoma were uneven soft tissue distribution in the antrum and tumor permeation with bone fragments remaining at the original tumor site. These findings may be helpful for distiguishing this cancer from benign chronic sinusitis and/or other malignant sinus disease. The pterygoid process, medial bony wall, and ethmoid sinus had a tendency to be spared in most of the 5 patients with second maxillary cancer compared to the 21 control cases. (orig.)

  9. Growth patterns of the maxillary sinus based on computed tomography

    The distance between two points in the bone and the angle of the bone wall were measured based on computed tomography imaging using Image Web Ver. 1.3 from Philips Electronics Japan, Ltd in order to investigate the growth patterns of the maxillary sinus. The results are as follows: Bone destruction and formation are simultaneously noted to occur in a forward direction in the normal anterior maxillary wall, with no thickening of the bone wall. The normal posterior maxillary wall grows in a forward longitudinal direction. The angle between the normal posterior and medial walls of the maxillary bone is 43 degrees, with no angle change is seen due to aging. The width of the alveolar process remains quite constant regardless of age, and the maxillary bone grows anteriorly, laterally, and inferiorly, terminating its growth at around 20 years of age. The balance between bone destruction and formation in the anterior maxillary wall can be disrupted due to inflammation, thus leading to bone thickening. Inflammation can also inhibit the longitudinal growth of the posterior maxillary wall, thus resulting in bone thickening. The balance between bone destruction and the formation in the posterior maxillary wall can be disrupted due to inflammation, thus leading to lateral thickening of the bone, and thereby resulting in an increase in the angular difference between the posterior and medial walls.

  10. A study of the distribution pattern and correlation between maxillary, frontal and sphenoid sinus volume

    In an attempt to study the distribution pattern and correlation between maxillary, frontal and sphenoid sinus volume, sinus volumes were measured by coronal CT scans of the paranasal sinus. Two hundred and four maxillary sinuses of 102 patients, the frontal sinuses of 62 patients and the sphenoid sinuses of 68 patients with no inflammatory changes detectable on CT scans of the each paranasal sinus and nasal cavity were analyzed. The volumes of the maxillary sinus showed a normal distribution, and its mean volume and standard deviation were 20.5±9.2 cm3. The logarithms of both frontal and sphenoid sinus volumes exhibited an normal distribution. The mean volume of the frontal sinus and the sphenoid sinus, which were calculated using logarithms of the sinus volumes statistically, were 8.3 cm3 and 9.6 cm3 respectively. The correlation coefficient was 0.134 between the maxillary and frontal sinus, 0.445 between the maxillary and sphenoid sinus and 0.315 between the frontal and sphenoid sinus. It is suggested that differences in the volume distribution pattern between the maxillary sinus and frontal or sphenoid sinus might be caused by differences in the growing process of each sinus.

  12. Ectopic Molar with Maxillary Sinus Drainage Obstruction and Oroantral Fistula

    Shahin Abdollahifakhim

    2013-06-01

    Full Text Available Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process.   Case report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected.   Discussions: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms.

  13. Maxillary sinusitis as a complication of infected dens invaginatus in maxillary lateral incisor: A case report

    Paras Mull Gehlot

    2015-01-01

    Full Text Available Introduction: Maxillary sinusitis can have various origins, including odontogenic origin. Case Report: We describe a case of maxillary sinusitis in a 25-year-old female patient who experienced pain and swelling in the right maxillary region as a complication of infected maxillary lateral incisor. Clinical and radiographic examinations revealed dens invaginatus (DI; Oehler′s type III associated with apical pathosis in the maxillary right lateral incisor, with a large periapical lesion involving the adjacent four teeth. Nonsurgical root canal treatment using calcium hydroxide medicament was carried out for all five teeth, which resulted in gradual diminution of sinusitis, and the patient remained asymptomatic. Discussion: This paper emphasizes the following: (i the challenges posed by DI for root canal treatment because of its anatomical complexity; (ii a nonsurgical approach in the management of a large periapical lesion, using calcium hydroxide medicament; and (iii the interdisciplinary management of conditions of common clinical concern for medical and dental practitioners, for successful outcome.

The author analyzed CT images of both left and right maxillary sinuses in 357 patients who visited Chonbuk National University Hospital between January 1997 and December 1998. The size and bone wall thickness of the maxillary sinus of normal, inflammatory and post-Caldwell-Luc groups were compared. The significant differences of transverse, maximum medio-lateral, maximum supero-inferior dimensions and medio-lateral dimension at nasal floor level between normal and post-Caldwell-Luc groups were found (P0.05). The significant differences of postero-lateral, infero-lateral and medial wall thickness between normal and post-Caldwell-Luc groups were found (P<0.05). The results of this study will aid in the diagnosis and treatment of maxillary sinus diseases and post operative treatment planning.

    Olfactory neuroblastoma (ONB) is a rare malignant tumor. Although the vast majority of cases arise in the nasal cavity, ONB is rarely reported in ectopic locations. We report a case of ONB in the maxillary sinus. A 63-year-old woman presented with left-sided nasal obstruction and epistaxis. Magnetic resonance imaging showed a nonenhancing left maxillary sinus tumor. Histologic sections showed ONB, Hyams grade IV, invading bone, skeletal muscle, and adjacent fibroadipose tissue. It is essential to be accurate when diagnosing sinonasal tumors because the differential diagnosis is broad, and one must consider the possibility of ectopic ONB, although it is rare. The behavior of ONB and other neuroendocrine tumors of the sinonasal region is quite different, and there are varied approaches to treatment. Therefore, an accurate diagnosis as well as correct grade and stage must be assigned. PMID:27180059

  18. A combined study of CT and MRI in chronic maxillary sinusitis

    With CT of the paranasal sinusitis mucosal swelling can not be distinguished from fluid accumulation within the sinuses in patients with chronic sinusitis. We studied 12 cases of chronic sinusitis (17 sides) by means of CT and MRI, with which we could distinguish mucosal swelling from fluid accumulation in the maxillary sinuses. It was found that in a majority of cases with total clouding of the maxillary sinus the degree of swelling of mucous membrane was relatively small. This indicates that the main cause of total clouding of the maxillary sinus found in CT is due to accumulation of fluid rather than from obliteration of the sinus due to swelling of mucous membrane within the maxillary sinus.

    Full Text Available Purpose: The aim of this study was to determine the prevalence and location of maxillary sinus septa with the help of dental volumetric tomography. Methods: 760 patients’ 1520 maxillary sinus were evaluated by dental volumetric tomography for detecting maxillary sinus septa. Maxillary sinus was divided into 3 zones (anterior, middle and posterior zones while location of the maxillary sinus septa. Results: 47 of maxillary sinus septa existed in the anterior zone (24.7%, 35 of them in the middle zone (18.4% and 108 of them in the posterior region (56.8%. Conclusion: The formation of the maxillary sinus septa was affected by the existence or lack of the teeth. Correct detection of the presence of maxillary sinus septa was important prior to sinus lifting and dental implant surgery. Dental volumetric tomographical evaluation of maxillary sinus septa was more useful for a correct diagnosis and treatment planning. [Cukurova Med J 2013; 38(3.000: 467-474

    Full Text Available Lasiodiplodia (monotypic comprises a very small proportion of the fungal biota. It is a common plant pathogen in tropical and subtropical regions. Clinical reports on its association with onychomycosis, corneal ulcer and phaeohyphomycosis are available. However, Lasiodiplodia theobromae causing fungal sinusitis has not been reported. We present here a case of fungal sinusitis in a 30-year-old woman, who came to the ENT OPD (out patient department with complaints of intermittent bleeding and nasal discharge from the left side for a week. The patient complained of headache, predominantly on the left side and heaviness on and off since two months. Diagnosis was based on radiological and mycological evidence; the patient underwent endoscopic surgery and was started on antifungal treatment.

  1. Assessment of the relationship between odontogenic maxillary sinusitis and findings in the ostiomeatal unit on coronal CT images

    The ostiomeatal unit (OMU) incorporates the maxillary sinus ostium, infundibulum, uncinate process, hiatus semilunaris ethmoid bulla, middle turbinate and middle meatus. The maxillary ostium is located in the superior portion of the medial maxillary wall and drains into the posterior aspect of the ethmoid infundibulum. The detailed anatomy of the OMU as displayed by CT provides a road map for surgeons prior to endoscopic sinus surgery. However, little attention has been paid to the relationship between the OMU and odontogenic maxillary sinusitis. This study examined the relationship between the osteomeatal unit and odontogenic maxillary sinusitis using coronal CT images. Materials consisted of 100 abnormal maxillary sinuses in 100 odontgenic maxillary sinusitis patients. Using coronal images, mucosal abnormalities were examined by grading expansion of the low density area, which represents the mucous membranes in the maxillary sinuses. Findings were classified into 3 types and the correlation between obstruction of the maxillary ostium and thickening of other sinonasal sinuses was examined. Results of the grading were as follows: 25 maxillary sinuses were graded as type 1, 22 maxillary sinuses as type 2, and 53 maxillary sinuses as type 3. On pattern analysis using coronal CT images, there were significant differences in obstruction of the maxillary ostium based on thickening of the mucous membranes of the odontgenic maxillary sinusitis (p<0.01); also there was a correlation between thickening of the mucous membranes of the ethmoid sinuses and thickening of the mucous membranes of the odontgenic maxillary sinusitis (p<0.01). Thickening of the mucous membranes of both the ethmoid sinuses and frontal sinuses was well correlated with obstruction of the maxillary ostium on coronal CT images (p<0.05). However, there was no correlation between obstruction of the maxillary ostium and sphenoid sinuses. Our study indicates that the severity of odontogenic maxillary

    We report an unusual case of a displaced maxillary molar and associated dentigerous cyst within the maxillary sinus in an adolescent presenting as recurrent sinusitis. Although a rare cause of sinusitis in children, dentigerous cysts should be included in the differential diagnosis for causes of persistent or recurrent sinusitis in this age group. This report provides further evidence for obtaining imaging studies when managing pediatric sinusitis that does not respond to standard antibiotic therapy. We discuss management options for these lesions including the differential diagnoses and need for follow-up. (orig.)

  4. A Peduncular Cystic Compound Odontoma on the Posterior Wall of the Maxillary Sinus

    A cystic compound odontoma in the maxillary sinus occurred in a 13-years-old boy, who had missing right upper third molar without having the history of extraction of the wisdom tooth. He complained nasal stuffiness, headache, and pain on the affected face, resembling any sign and symptoms of the maxillary sinus problems. The cysteic compound, sized 2 x 1.5 cm in diameter was pedunculated and attached on the posterior wall of the right maxillary sinus and above the antral floor. The location of the compound odontoma in the maxillary sinus was confirmed after panoramic, waters, spiral tomographic, CT examinations and surgical exploration. Irs location was on the medical, posterior, superior to the normal position of the maxillary third molar or the maxillary dental arch. The cystic odontoma in the maxillary sinus made the patient have the sings and symptoms of maxillary sinusitis. The cystic compound odontoma might be originated from the dental lamina of the missing upper right third molar. The 'V principle' of the upper jaw growth and the pneumatization process of the maxillary sinus could explain why the compound odontoma had peduncular shape and the location of odontoma was on the medial, superior to the normal position of the maxillary dental arch.

  6. Evaluation of the postoperative maxillary sinus with computed tomography

    To evaluate the computed tomographic appearances of postoperative maxillary sinuses. 33 asymptomatic cases of post-operative maxillary sinus without evidence of any pathologic changes and clinical symptoms were selected. CT images were classified as opacification, soft tissue shadow, anterior wall depression, nasoantral communication, and compartmentalization. The relationships between the CT image and the age of patients at the time of operation, and between the CT image and the duration of time elapsed since the surgical procedure were evaluated. The most commonly presented radiological characteristics that occurred after the Caldwell-Luc procedure were opacification and soft tissue shadow. Anterior wall depression and nasoantral communication were radiographic indications that a Caldwell-Luc operation had been carried out. The age of patients when they had been first operated on, and the duration between the surgical procedure and the time of evaluation had no effect on the CT appearances of normal changes. In cases involving a longer time interval between the antral surgery and evaluation, the anterior wall depression with bony healing was more commonly observed than soft tissue healing. The radiographic information regarding the normal healing state using computed tomography can distinguish post-operative changes from inflammatory and cystic disease in patients who have undergone a Caldwell-Luc type of radical maxillary astronomy.

  7. Radiodense concretions in maxillary sinus aspergillosis: pathogenesis and the role of CT densitometry

    The purpose of this study was to investigate by CT the origin of radiodense maxillary sinus concretions and whether CT densitometry is effective in the prediction of maxillary sinus aspergillosis and in the differentiation of the origin of these concretions. In a prospective study in 21 patients with radiodense maxillary sinus concretions detected by radiography, a preoperative CT study of the paranasal sinuses and the concretions was undertaken. Additional scans of the upper alveolar ridge were also performed. Radiological findings were compared with clinical symptoms and with CT findings, especially CT densitometry of the sinus concretions and dental root-filling material. All patients underwent a functional Caldwell-Luc operation; histological and microbiological examinations were performed. Fifteen of the 21 patients (71.4%) with radiodense concretions had a histological and microbiological diagnosis of sinus aspergillosis. The sinus concretions had CT densities higher than 2000 HU (Housfield units) in 15 patients and lower than 2000 HU in 6. Fourteen of 15 patients (93.3%) with concretions ahving CT densities higher than 2000 HU had a postoperative diagnosis of maxillary sinus aspergillosis. The mean CT density of the sinus concretions in patients with maxillary sinus aspergillosis was 2868 HU (range 1870-3070 HU), and in patients without aspergiollosis was 778 HU (range 228-2644 HU). The mean CT density of the dental root-filling material was 2866 HU (range 2156-3070 HU). Paranasal sinus CT with CT densitometry of a sinus concretion has a higher accuracy than standard radiogrpahy and clinical findings in the prediction of maxillary sinus aspergillosis (93.3% vs 71.4%). CT densitometry helps to confirm the dental origin of maxillary sinus concretions and to explain a possible dental pathogenesis of maxillary sinus aspergillosis. (orig.)

    Physicochemical characteristics of a biomaterial directly influence its biological behavior and fate. However, anatomical and physiological particularities of the recipient site also seem to contribute with this process. The present study aimed to evaluate bone healing of maxillary sinus augmentation using a novel bioactive glass ceramic in comparison with a bovine hydroxyapatite. Bilateral sinus augmentation was performed in adult male rabbits, divided into 4 groups according to the biomaterial used: BO-particulate bovine HA Bio-Oss(®) (BO), BO+G-particulate bovine HA + particulate autogenous bone graft (G), BS-particulate glass ceramic (180-212 μm) Biosilicate(®) (BS), and BS+G-particulate glass ceramic + G. After 45 and 90 days, animals were euthanized and the specimens prepared to be analyzed under light and polarized microscopy, immunohistochemistry, scanning electron microscopy (SEM), and micro-computed tomography (μCT). Results revealed different degradation pattern between both biomaterials, despite the association with bone graft. BS caused a more intense chronic inflammation with foreign body reaction, which led to a difficulty in bone formation. Besides this evidence, SEM and μCT confirmed direct contact between newly formed bone and biomaterial, along with osteopontin and osteocalcin immunolabeling. Bone matrix mineralization was late in BS group but became similar to BO at day 90. These results clearly indicate that further studies about Biosilicate(®) are necessary to identify the factors that resulted in an unfavorable healing response when used in maxillary sinus augmentation.

  9. Maxillary Sinus Inflammatory Myofibroblastic Tumors: A Review and Case Report

    Chase C. Hansen

    2015-01-01

    Full Text Available An inflammatory myofibroblastic tumor (IMT is an immunohistochemically diverse entity demonstrating neoplastic and nonneoplastic qualities. Although IMTs can arise in any area of the body, lesions arising in certain sites, namely, the nasal cavity, paranasal sinuses, and pterygopalatine fossa, demonstrate a heightened neoplastic and invasive potential. Despite case specific complete tumor regression and disease remission in response to pharmacotherapeutics, a subset of IMTs remain resistant to all forms of therapy. We present such a case, a 34-year-old female patient, with a highly resistant, maxillary sinus IMT. Her refractory, ALK-1 negative IMT has not responded well to novel therapies reported in current literature. This case suggests the role of zonal expressivity within a single lesion as a probable mechanism for its highly resistant nature and should promote determination of each IMT’s cytogenetic profile to provide more effective targeted therapy. Paper includes a literature review of all maxillary sinus IMTs from 1985 to 2014 along with their immunohistochemical staining, treatments, and outcomes.

  10. Maxillary sinus 3D segmentation and reconstruction from cone beam CT data sets

    Purpose: Segmentation of the maxillary sinuses for three-dimensional (3D) reconstruction, visualization and volumetry is sought using an automated algorithm applied to cone beam computed tomographic (CBCT) data sets. Materials and methods: Cone beam computed tomography (CBCT) data sets of three subjects aged 9, 17, and 27 were used in 3D segmentation and reconstruction. The maxillary sinuses were obtained by propagation from one start point in the right sinus and one start point in the left sinus to the whole regions of both sinuses. The procedure was based on voxel intensity distributions and common anatomic structures, specifically each middle meatus of the nasal cavity. A program was written in C++ and VTK languages to demonstrate the surface topological shapes of the maxillary sinuses. Results: The developed segmentation algorithm separated maxillary sinuses successfully permitting accurate comparisons. It was robust and efficient. 3D morphological features of the maxillary sinuses were observed from three human subjects. Conclusions: Automated segmentation of maxillary sinuses from CBCT data sets is feasible using the proposed method. This tool might be useful for visualization, pathological diagnosis, and treatment planning of maxillary sinus disorders. (orig.)

    We evaluated histologically and tomographically the effects of fresh frozen bone allograft (FFB) or bovine bone mineral (BBM) in maxillary sinus floor augmentations. In total, 30 maxillary sinuses from 30 patients (mean age = 51.17 ± 10.86 years) underwent sinus augmentation. Patients were divided in two test groups (15 sinuses each). The first group was grafted with allograft bone, and the second group received bovine bone mineral. After 6 months, bone samples from each group were collected for histological examination. Implant survival rates were 97.78% (FFB group) and 100% (BBM group) 6 months after functional loading. Median volumetric reductions of 31.2% (11.33-40.56) and 12.22% (9.91-20.59) were observed in the FFB and BBM groups, respectively. Comparisons between the groups for differences in initial and final volumes of bone (p = 0.015) and the rate of resorption (p = 0.009) showed statistically significant differences. The FFB group showed osteoblastic cells in close contact with osteoid matrix, connected through bridges between allograft bone particles and new bone formation. The BBM group showed BBM particles in close contact with new bone, with visible osteoid matrix bridges and osteoblastic cells surrounding it. None showed signs of acute or chronic inflammatory infiltrate. Despite better results with BBM, both FFB and BBM in maxillary sinus augmentation resulted in high percentages of new bone formation, and allowed implant placement with a low rate of failure of osseointegration at a 6-month follow-up.

  12. Computed tomography measurements of different dimensions of maxillary and frontal sinuses

    We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the paranasal sinuses, especially the thickness of the anterior wall of the maxillary sinus (at the canine fossa). To the best of our knowledge, this is the first report on the thickness of the canine fossa. This study aimed to (a) estimate different dimensions of the maxillary and frontal sinuses measured on computed tomography (CT) of the head, (b) define cut-off values for the normal upper and lower limits of the different measured structures, (c) determine differences in age, side and gender, (d) compare manually and automatically estimated maxillary sinuses volumes, and (e) present incidental findings in the paranasal sinuses among the study patients. Dimensions of 120 maxillary and frontal sinuses from head CTs were measured independently by two radiologists. The mean value of the maxillary sinus volume was 15.7 ± 5.3 cm3 and significantly larger in males than in females (P = 0.004). There was no statistically significant correlation between the volume of maxillary sinuses with age or side. The mean value of the bone thickness at the canine fossa was 1.1 ± 0.4 mm. The automatically estimated volume of the maxillary sinuses was 14-17% higher than the calculated volume. There was high interobserver agreement with regard to the different measurements performed in this study. Different types of incidental findings of the paranasal sinuses were found in 35% of the patients. We presented different dimensions of the maxillary and frontal sinuses on CTs. We believe that our data are necessary for further development of a clinically applicable Doppler equipment for staging rhinosinusitis

    Full Text Available Introduction: Ameloblastic fibro-odontoma is a rare, benign, asymptomatic tumor. The term ameloblastic fibro-odontoma was first used by Hooker in 1967 as a separate lesion from ameloblastic odontoma.   Case Report: This case report describes an eleven years old female with large ameloblastic fibro-odontoma in the right maxillary sinus.   Conclusion: There is a low potential for recurrence after complete Enucleation of ameloblastic fibro-odontoma, but due to the risk of ameloblastic sarcoma after recurrence, the surgery should be perfect along with a careful follow up. 

  15. Maxillary sinus marrow hyperplasia in sickle cell anemia

    Marrow hyperplasia is a sequela of sickle cell anemia (SCA) and may be seen in the skull in children after 5 years of age. The facial bones, except for the mandible and orbits, are usually not involved. We report an unusual case of a 28-month-old black boy with SCA who presented with extensive marrow hyperplasia of the maxillary sinuses in addition to severe calvarial and mandibular changes. The imaging characteristics on CT (similar to other sites of marrow hyperplasia) and MR (low signal on both T1 and T2 sequences) should aid in making the correct diagnosis. (orig.)

    To determine whether the wall thickening of the maxillary sinus is a characteristic finding in aspergillosis. In 103 patients, including 26 with aspergillosis, 21 with inverted papilloma (IP), and 56 with unilateral chronic sinusitis, the thickness of the maxillary sinus wall was determined by CT scanning. All cases were proven pathologically, and patients with a history of previous surgery of bone destruction were excluded. Two neuroradiologists retrospectively reviewed the CT scans using bone window settings for sinus wall hyperostosis and the presence of intrasinus calcification. Thickening of the maxillary sinus wall was assessed visually in a semiquantitative manner, and graded as 'none' (absence of thickening), 'mild' (thickening of up to 1.5 times), or moderate ot severe(over 1.5 times thicker than normal contralateral sinus wall at its thickest point). Moderate to severe wall thickening was found only in patients with aspergillosis (21/26, 80.8%). Mild wall thickening was seen in two patients with aspergillosis (2/26, 7.7%), in 12 of 21 with IP (57.1%), and in 5 of 56 with chronic maxillary sinusitis (8.9%). Most cases of chronic maxillary sinusits( 51/56,91.1%), 9/21 IP cases (42.9%), and 3/26 cases of aspergillosis (11.5%) showed no thickening of the maxillary sinus wall. Calcifications were found in 18 patients with aspergillosis (69.2%), in no patient with IP (0%), and in one with chronic maxillary sinusitis (1.8%). We suggest that 'moderate to severe' wall thickening of the maxillary sinus is the characteristic finding of aspergillosis. Although various sinonasal diseases can cause bone change, CT findings of hyperostosis of the maxillary sinus and intrasinus calcification are very helpful in differentiating fungal sinusitis from other types of chronic inflammatory lesions.

  19. A combined frontal and maxillary sinus approach for repulsion of the third maxillary molar in a horse.

    Boutros, C P; Koenig, J B

    2001-01-01

    The 3rd maxillary molar is a difficult tooth to remove by extraction or repulsion. A combined frontal and maxillary approach provides good exposure for repulsion of this tooth, debridement of the sinuses, and placement of an alveolar seal. The improved exposure should minimize operative difficulties and postoperative complications.

    Maxillary sinusitis can cause pain or discomfort to the maxillary dentition but no report of patients complaining of a "jumping tooth sensation" during sinusitis has been recorded in the literature. This article presents a case of an unusual localised sensation from a maxillary right second premolar experienced while undergoing root canal treatment. This sensation was felt during walking while the patient was suffering an episode of influenza. This sensation first occurred following debrideme...

  1. CT findings of malignant tumors of maxillary sinus

    CT findings of histologically proven malignant tumors of maxillary sinus in 36 patients were retrospectively analyzed. A variety of malignant tumors were included; 27 cases of squamous cell carcinoma, 3 malignant lymphomas, 2 malignant melanomas, 2 rhabdomyosarcomas, and chondrosarcoma, adenoid cystic carcinoma, and malignant ameloblastoma. CT staging was T4 in 19 cases, T3 in 16 cases and T2 in 1 case. The most common involved area beyond maxillary antrum was nasal cavity (25 cases), followed by ethmoid sinus (20 cases), orbit (19 cases), infratemporal fossa (17 cases), check skin (13 cases), pterygopalatine fossa (10 cases), and nasopharynx (6 cases). Skeletal destruction was seen in medial wall of antrum (31 cases), posterior wall of antrum (25 cases), anterior wall of antrum (23 cases), roof of antrum (19 cases), lamina papyracea (6 cases), and lateral wall of orbit (5 cases) in that order of frequency. Lymph node metastases were found in 2 cases of malignant melanoma, 2 cases of malignant lymphoma, and chondrosarcoma, squamous cell carcinoma, and malignant ameloblastoma. Predilection site of lymph node involvement was submandibular (3 cases), internal jugular (2 cases), parotid (2 cases), and retropharyngeal node (1 case)

  2. Primary malignant lymphoma of the maxillary sinus: CT and MRI

    We reviewed the CT and MRI of seven patients with primary malignant lymphoma of the maxillary sinus to find if there are characteristic imaging findings suggestive of the disease. The images were analysed for appearance, size, signal, internal characteristics, extent of tumour, bone change and lymph node enlargement. In two patients, the tumour first presented with mucosal thickening. In the remaining five, the tumours were an expansile mass 4-6 cm in diameter at the time of detection. Although it was difficult to distinguish tumour from mucosa or obstructed fluid on CT, T2-weighted MRI enabled us to separate tumour from normal mucosa or fluid. In two patients, the tumours were heterogeneous. Calcification and haemorrhage were observed in one patient. Periantral soft-tissue infiltration was always present, even when tumour appeared as slight mucosal thickening. Posterior extension was seen in all patients. Permeative and lytic bone destruction accompanied most cases of periantral soft-tissue infiltration; mixed destruction and sclerosis was also observed. Mucosal thickening with periantral soft-tissue infiltration may suggest malignant lymphoma of the maxillary sinus in its early form.

  4. A radiographic study of experimentally produced bone defects in the posterior wall of the maxillary sinus

    The purpose of this study was to evaluate the ability of radiographs in detecting experimental bony defect in the posterior wall of the maxillary sinus. For this study, experimentally five skulls were used, the bony defects with a diameter of 5 mm were created at different locations in the posterior wall of the right maxillary sinus and the bony defects of 10 mm were created at different locations in the posterior wall on left maxillary sinus. Panoramic view, panoramic sinus view, water's view, and computed tomogram were taken and the results analyzed. The obtained results were as follows : 1. The panoramic view was superior to the panoramic sinus view in detecting the bony defects in the posterior wall of the maxillary sinus. 2. Panoramic view, panoramic sinus view, and waters' view were limitation to the detection of the bony defects in the posterior wall of the maxillary sinus. 3. All the bony defects in the posterior wall of the maxillary sinus were excellently visualized on the computed tomogram.

    1998-02-15

    In this study, radiographic evaluation was made using panoramic radiography and cross-sectional tomography of SCANORA in male and female adults in their 20 s on the relationship between the maxillary sinus floor and the apex of the maxillary molar, to test the accuracy and effectiveness of the cross-sectional tomography, and to use this information in the assessment of preop, and postop, root canal treatment, apical surgery, extraction and implantology. Forty-one adults with an average age of 24.4 years were studied panoramic radiography and cross-sectional tomography. In panoramic view and cross-sectional view, the position of the apices of maxillary molars were classified as separated, contacted, or protruded type; the general shape of the maxillary sinus floor was evaluated horizontally and vertically from cross-sectional tomography. The accuracy of each radiography was tested using maxilla from 5 fresh cadavers from the Anatomy Lab at Yonsei University Dental College, and panoramic view and cross-sectional tomography were taken in the same condition as with the patients. The results were as follows: 1. Panoramic view and cross-sectional view were taken in the maxilla specimen, and the actual distance between the maxillary sinus floor and the tooth apices were measured in the specimen; the median values of the distance from the tooth apices to the maxillary sinus floor in the panoramic view, cross-sectional view and in the accrual maxilla specimen were 2.83 mm, 4.51 mm, and 4.15 mm, respectively. In the cross-sectional view, the measured distance was close to the actual distance but in the panoramic view, the measured distance was far from the actual distance. 2. When the results of the panoramic view and cross-sectional view were compared, 40.5% of the results agreed with each other in the two radiographic methods and buccal roots of the 2nd molar were the closest to the maxillary sinus floor in the cross-sectional tomography.3. In cross-sectional view, when

  8. The role of proper treatment of maxillary sinusitis in the healing of persistent oroantral fistula

    David B. Kamadjaja

    2008-09-01

    Full Text Available Background: Oroantral communication (OAC is one of the possible complications after extraction of the upper teeth. If not identified and treated properly, a large OAC may develop into oroantral fistula (OAF which means that there is a permanent epithelium-lined communication between antrum and oral cavity. Such fistulas may cause ingress of microorganism from oral cavity into the antrum leading to maxillary sinusitis. Oroantral fistula usually persists if the infection in the maxillary antrum is not eliminated. Therefore, treatment of oroantral fistula should include management of maxillary sinusitis in which surgical closure of oroantral fistula should be done only when the sinusitis has been cured. Purpose: This case report emphasizes on the importance of proper management of maxillary sinusitis in the healing of oroantral fistula. Case: A case of an oroantral fistula following removal of upper left third molar is presented. As the maxillary sinusitis was not identified pre-operatively, two surgical procedures to close the fistula had ended up in dehiscence. Case management: The diagnosis of maxillary sinusitis was finally made and the sinusitis subsequently treated with combination of trans-alveolar sinus wash out, insertion of an acrylic splint, and two series of nasal and sinus physiotherapy procedures. The size of the defect decreased gradually during the treatment of the sinusitis and finally closed up without any further surgical intervention. Conclusion: This case report points out that it is important to detect intraoperatively an antral perforation after any surgery of the maxillary teeth and to close any oroantral communication as early as possible and that it is important to treat properly any pre-existing maxillary sinusitis before any surgical method is done to close the fistula.

  9. A study on morphology of maxillary sinus by using the orthopantomograms

    This study was performed in order to analyse the morphology of maxillary sinus on orthopantomogram. The author analysed the anterior-posterior width of mesial wall, the extension of anterior margin in maxillary sinus and the interrelation between the root apex of maxillary 1st molar and sinus floor. The films consisted of 514 orthopantomograms divided into three groups ranging the 3rd decade, 4th and 5th decade and 6th decade. The obtained results were as follows: 1. The mean dimensions of the anterior-posterior width of mesial wall were 43.81 ± 4.55 mm for male and 43.80 ± 4.49 mm for female in the right of maxillary sinus, 43.75 ± 4.74 mm for male and 43.37 ± 3.92 mm for female. 2. With age, the dimensional change of the anterior-posterior width of mesial wall in maxillary sinus was not observed. 3. The extension order of anterior margin of the maxillary sinus was distal to canine side, 1st premolar mesial side, canine mesial side, and 1st premolar distal side. 4. In the distance between the root apex of upper 1st molar and the maxillary sinus floor, the degree of closeness was more increased in the older-aged group than in the younger-aged group.

  10. Differential radiologic diagnosis of the spherical shades found in the maxillary sinus

    Data, obtained during clinical and radiologic examination of 203 patients have been analysed. It was found that the error percentage in diagnosis of the spherical shades in the maxillary sinuses reaches 22 % according to plain radiography of the nasal sinuses. A radiologic sympton of the spherical shade in the lumen of the maxillary sinus may be detected either in bening processes (retentive and odontogenic cysts, bening tumors, fibrous dysplasia of the jaws, etc.), or in malignant tumors, originating from the alveolar process area and the hard palate. Some radiologic signs of the most common diseases, accompanied by the sherical shade sympton in the lumen of the maxillary sinus, are described. A verification of both localization and nature of pathologic process in the maxillary sinus is carried out by means of multiposition craniography and various modifications of the stratifying X-ray examination

    2010-05-01

    Diagnosing sinusitis remains a challenge for primary care physicians. There is a need for a simple, office-based technique to aid in the diagnosis of sinusitis without the cost and radiation risk of conventional radiologic imaging. We designed a low-cost near-infrared (NIR) device to transilluminate the maxillary sinuses. The use of NIR light allows for greater interrogation of deep-tissue structures as compared to visible light. NIR imaging of 21 patients was performed and compared with computed tomography (CT) scans. Individual maxillary sinuses were scored on a scale from 0 to 2 based on their degree of aeration present on CT and similarly based on the NIR signal penetration into the maxilla on NIR images. Our results showed that air-filled and fluid/tissue-filled spaces can be reasonably distinguished by their differing NIR signal penetration patterns, with average NIR imaging scores for fluid-filled maxillary sinuses (0.93+/-0.78, n=29) significantly lower than those for normal maxillary sinuses (1.62+/-0.57, n=13) (p=0.003). NIR imaging of the sinuses is a simple, safe, and cost-effective modality that can potentially aid in the diagnosis of sinusitis. Long-term, significant device refinement and large clinical trials will be needed to determine the diagnostic accuracy of this technique.

  12. CT findings of change of the maxillary sinus after caldwell-luc operation

    This study describes the CT findings of changes in the maxillary sinus after the Caldwell-Luc procedure. The maxillary sinus-related findings in 35 cases among 20 patients (17 cases in 10 males and 18 cases in 10 females) who had undergone the Caldwell-Luc procedure mean 14.6 years earlier were reviewed. CT scans were obtained in the axial and coronal planes, with 5mm thickness. By means of the T test, changes in the size of the bony wall of the maxillary sinus, as well as antral volume change, were compared with normal maxillary sinus group (41 male and 23 female cases). Males and females were compared separately, and surgical bony defect of naso-labial antrotomy and nasoantral window, fibro-osseous proliferation, compartmentation and mucosal thickening of the postoperative maxillary sinus were evaluated, as were findings of chronic or recurrent maxillary sinusitis and postoperative complications. Naso-labial antrotomy was clearly identified in 27 of 35 cases, and irregular bony surface in the remaining eight, as were 27 bony defects and one irregular bony margin among a total of 28 cases of nasoantral window. Due to shortening of the height of the orbit, reductions in maxillary width, nasoantral communication width and anteroposterior diameter of the maxilla, and widening of the width of the inferior meatus, the maxillary sinus tended to become hypoplastic and centripetally contracted. Reduced cavitary volume of the maxillary sinus was noted (p less than 0.05), and fibro-osseous proliferation (n=3D29), compartmentation (n=3D11), and mucosal thickening (n=3D22) of the postoperative maxillary sinus were also seen. There were findings of chronic sinusitis (n=3D22), as well as complications of postoperative mucocele (n=3D3) and oroantral fistula (n=3D2) of the maxillary sinus. The characteristic maxillary sinus-related findings seen after the Caldwell-Luc procedure are helpful in distinguishing postoperative change from recurrent paranasal diseases and resulting

    Zargaran

    2015-06-01

    Full Text Available Introduction Calcifying odontogenic cyst (COC is an uncommon odontogenic lesion, classified in two variants: the cystic variant and neoplastic (solid variant. Case Presentation This case report presents multiple COC, which involved the maxillary bone and sinus in a 30-year-old man. Several of these lesions were cystic, while the others were neoplastic in type, and the lesions were removed surgically. Discussion Based on a literature review available on this topic in English, our case study was found to be the first one with multiple COC, showing both the cystic and neoplastic histopathological variant. Considering the high rate of recurrence of neoplastic COC, the patients should benefit from a long follow-up after treatment.

  14. Radiotherapy of maxillary sinuses carcinoma: state of art

    Maxillary sinus carcinomas are rare malignancies of the face, characterized by high local relapsing rate. Modalities of treatment are without consensus and respective roles of radiation therapy and surgery remain controversial. As those malignancies are often diagnosed at locally advanced stage, radiation therapy may frequently be used for patients having unresectable advanced disease. Nevertheless, surgery remains treatment of choice for more localized malignancies, in association with systematic postoperative radiotherapy. For those patients whose prognosis remains pejorative, it is necessary to precise the role of radiotherapy in first intention for inoperable tumors, to define necessity for nodal treatment performing and evaluate the place of neo-adjuvant or concomitant chemotherapy in a multimodal strategy.

  15. A comparative study of radiographic images of maxillary sinusitis

    The purpose of this study was to evaluate the Waters' views, panoramic and periapical radiograms as well as clinic al symptoms in the diagnosis of maxillary sinusitis. The author analyzed the types of mucosal thickenings, the types of bony wall changes, the pathologic changes of antra l floors and total amount of agreement on radiograms in 495 patients with 505 maxillary sinuses which demonstrated radio graphic changes. The results were obtained as follows : 1. 125 cases (24.8%) showed the mucosal thickening of antral floor and lateral wall (Type II), 106 cases (20.9%) showed the mucosal thickening around the whole antral wall (Type IV) and 75 cases (14.8%) showed increased radiopacity of whole antrum. 2. Among 505 cases of mucosal thickening, 319 cases (63.2%) showed the bony wall changes : 114 cases (35.9%) showed the thining of lateral walls, 105 cases (32.8%) showed the thickening of lateral walls and 47 cases (14.7%) showed indistinct antral walls. 3. Among 6 types of mucosal thickenings, the incidence of bony wall changes was high in type VI (73.3%) and in type IV (71.6%). 4. 139 cases (25.1%) showed no pathologic change of antral floor, 127 cases (22.9%) showed the indistinct antral floor and 022 cases (22.1%) showed the halo appearance of antral floor on panoramic and periapical radiograms. 5. 449 cases (88.9%) showed apparent increased radiopacity and 47 cases (9.3%) showed suspicious increased radiopacity on Waters' views. 280 cases (71.6%) showed apparent increased radiopacity and 88 cased (22.5%) showed suspicious increased radiopacity on panoramic radiograms. And 141 cases (31.6%) showed apparent increased radiopacity and 133 cases (33.4%) showed suspicious increased radiopacity on periapical radiograms.

  16. Automatic region detection of maxillary sinus from human face radiographs in the assessment of recovery in chronic sinusitis

    Automatic region detection of the maxillary sinus from human face X-ray pictures is studied and presented. Firstly a new algorithm for transformation from X-ray images to bi-level images is introduced, which is based on the local properties of the images. Secondly, a region detection algorithm is used to determine global shape parameters of the maxillary sinus such as area, perimeter length, and complexity. It is shown that the regions of the maxillary sinus detected by the new algorithm coincide well with clinical diagnosis. It is also shown that the cumulative distribution function calculated from the density histogram of detected regions is a useful parameter for assessing the stage of recovery in chronic sinusitis.

  19. A study of geometrical theory for maxillary sinus projection in children

    This study is to evaluate the individual angulation on maxillary sinus projection and establishing angulation in children by new geometrical method. There were two groups, which are 60 cases in children (ranged from 1yr to 3yrs, 3yrs to 8yrs, 8yrs to 12yrs) and 50 cases in adults. We analyzed the true lateral maxillary sinus film of total 110 patients using new geometrical method. We demonstrated an angle of maxillary sinus projection. Arithmetical it is not valid during development of facial bone in childhood. The individual range of angulation according to age was that 1yr to 3yrs is 50-47 degrees, 3yrs to 8yrs is 47-40 degrees, 8yrs to 12yrs is 40-38 degrees. This geometrical method will be useful in establishing angulation for maxillary sinus projection

  2. The coronal CT of the paranasal sinuses in the postoperative maxillary cyst

    We classified patients with paranasal sinus disease into 3 categories, those with or without a history of previous Caldwell-Luc procedure according to clinical diagnosis. Class A: post-operative maxillary cysts in 22 patients. Class B: paranasal sinusitis in 21 patients who had undergone Caldwell-Luc surgery. Class C: paranasal sinusitis in 62 patients who had not undergone paranasal sinus surgery. This study evaluated the ethmoid, frontal and sphenoid sinuses in these 3 classes of patients on coronal CT scan. High density areas in the ethmoid sinuses were observed in 25.0% of class A, 80.0% of class B, and 82.1% of class C; in the frontal sinuses in 19.0% of class A, 73.7% of class B, and 73.3% of class C; in the sphenoid sinuses in 18.2% of class A, 57.1% of class B, and 51.6% of class C. As a result, the prevalence of high density areas in the ethmoid, frontal and sphenoid sinuses in patients (class A) with postoperative maxillary cysts was significantly lower than those in patients (classes B and C) with paranasal sinusitis. The authors speculated that postoperative maxillary cysts arise in cases that had few or lightly inflammatory changes of the ethmoid, frontal and sphenoid sinuses. (author)

  4. Radiotherapy for cancer of the maxillary sinus, with boost therapy by low dose rate intracavitary irradiation

    Prognosis of cancer of the maxillary sinus markedly depends on its local control. In order to increase the local control rate for cancer of the maxillary sinus, low dose rate intracavitary irradiation of the maxillary sinus was performed as boost therapy of external irradiation. During the period from January 1975 through September 1982, 87 patients with cancer of the maxillary sinus were treated by radiotherapy at the Department of Radiology, The Jikei University School of Medicine, and 43 out of these 87 cases were treated with intracavitary irradiation as boost therapy of external irradiation. The 3-year and 5-year cumulative survival rates of the 43 cases treated with intracavitary irradiation were 44% and 39%, respectively. The same two rates of the 44 cases without intracavitary irradiation were both 47%. Considering that tumor foci still persisted in the maxillary sinus in almost all of the 43 intracavitary irradiation cases and that 34 of them were of the postero-superior type (according to Oehngren's classification), which generally results in poor prognosis, intracavitary irradiation as boost therapy can be assumed to be one of the effective therapeutic techniques for cancer of the maxillary sinus.

  5. Does hyrax expansion therapy affect maxillary sinus volume? A cone-beam computed tomography report

    The aim of this study was to investigate the initial effects of maxillary expansion therapy with Hyrax appliance and to evaluate the related changes in maxillary sinus volume. Thirty patients (20 females, 10 males; 13.8 years) requiring maxillary expansion therapy, as part of their comprehensive orthodontic treatment, were examined. Each patient had cone-beam computed tomography (CBCT) images taken before (T1) and after (T2) maxillary expansion therapy with a banded Hyrax appliance. Multiplanar slices were used to measure linear dimensions and palatal vault angle. Volumetric analysis was used to measure maxillary sinus volumes. Student t tests were used to compare the pre- and post-treatment measurements. Additionally, differences between two age groups were compared with Mann-Whitney U test. The level of significance was set at p=0.05. Comparison of pre-treatment to post-treatment variables revealed significant changes in the transverse dimension related to both maxillary skeletal and dental structures and palatal vault angle, resulting in a widened palatal vault (p<0.05). Hard palate showed no significant movement in the vertical and anteroposterior planes. Nasal cavity width increased on a mean value of 0.93 mm(SD=0.23, p<0.05). Maxillary sinus volume remained virtually stable. No significant age differences were observed in the sample. Hyrax expansion therapy did not have a significant impact on maxillary sinus volume.

  7. A radiographic study of the experimental lesions in the maxillary sinus

    The purpose of this study was to examine the differences in representation of a globular radiopaque mass on the pantomograms and Waters' views and to compare the efficacy of periapical radiograms, pantomograms and Waters' views in detection of defects on the internal walls of the maxillary sinus. This study was performed with dried human skull. For the study of difference of radiopaque mass shadow in the two views, rubber ball with a diameter of 10mm was used as the experimental lesion. It was placed successively on the internal wall of the anterior, posterior, medial, lateral walls and floor of the maxillary sinus. To examine the detectability of defects for radiographic techniques, defects were formed in the anterior, posterior, medial, lateral walls, and floor of the maxillary sinus. They were formed with 0.5 mm, 0.75 mm, 1.0 mm, 2.0 mm and 3.0 mm sized steel round burs with a slow speed dental handpiece. By subsequently plugging the holes with zinc oxide eugenol paste, radiopaque defects were produced. After that the periapical radiograms, the pantomograms and the Waters' views were taken each and every defect. The obtained results were as follows: 1. Rubber balls placed on each internal wall of maxillary sinus were correctly depicted on the posterior wall and the floor in case of the pantomogram, and on the anterior wall and the medial wall in case of the Waters' view. 2. On the detectability of defects for each radiographic technique, radiolucent defects were detected in different places of each technique. Periapical radiogram could detect 1.0 mm defect on the floor of the maxillary sinus, pantomogram could detect 2.0 mm defect on every internal wall of the maxillary sinus, and Waters' view could detect 3.0 mm defect on the anterior wall of the maxillary sinus. 3. On the detectability of defects for each radiographic technique, radiopaque defects were detected in different places for each technique. Periapical radiogram could clearly detect 0.5 mm defect on

  9. Morphological study of the maxillary sinus using three-dimensional reconstruction of the tomographic images

    A morphological study of the maxillary sinus using the computerized three-dimensional reconstruction of the tomographic images was made. Materials of this study were 86 adult dry skulls of the Second Department of Oral Anatomy of Fukuoka Dental College. The results were as follows: 1. A tomographic apparatus which could select varius X-ray tube shifts was used. The hypocycloidal shift was the best for the tomography of the maxillary sinus. 2. In the tomographs of the maxillary sinus, the images of some sections in the maximum cross-section area presented real shapes. However, the images of other sections were indistinct and influenced by the shape of the maximum cross-section. 3. Reconstruction of the tomographic images of the maxillary sinus by computer made it easy and precise to recognize the three-dimensional image. 4. The dimensions in the maximum cross-section of the maxillary sinus of the 86 adult dry skulls obtained from the reconstructed three-dimensional images were 4.59 ± 1.26 cm2 in frontal, 5.21 ± 1.36 cm2 in transversal and 8.09 ± 1.82 cm2 in sagittal tomographs. The majority of the skulls were symmetry, and a few were asymmetry in correlation between the right and left side sinuses. 5. According to the reconstructed three-dimensional images the shapes of the maxillary sinus of the 86 adult dry skulls were classified into 10 types in frontal, 4 types in transversal and 8 types in sagittal tomographs. The most familiar shape was triangular in frontal, trapezoidal in sagittal and triangular in transversal tomographs. 6. The dimension and shape of the maxillary sinus had no correlation with the frontal width of the nasal cavity. (author)

  10. A case report of an inverted papilloma infiltrating into maxillary sinus

    The present study reports a case of inverted papilloma of the nasal cavity and infiltrating into the maxillary sinus. Inverted papilloma is an uncommon and locally aggressive benign tumor of the sinonasal region. The patient, 51-year-old male, presented with unilateral nasal obstruction and periodic swelling on the palate without pain. Enhanced CT scan revealed a heterogeneously enhancing solid mass in the nasal cavity and infiltrating into the right maxillary sinus, as well as an incidental, secondarily infected residual cyst in the periapical area of the right maxillary canine. The sinonasal mass was revealed as an inverted papilloma on histopathologic examination.

    This report was to show the radiographic appearances of the fungus ball in a paranasal sinus and to emphasize the scan area of cone beam computed tomography (CBCT) to detect the calcification in the paranasal sinus. A seventy four-year-old woman visited our department for the implant rehabilitation at both maxillary posterior edentulous region. Pre-operative radiographic examinations including the panoramic, CBCT, and multidector CT images were taken. An opacification in the right maxillary sinus was observed on the multiplanar image of CBCT, however the pre-determined scan area of CBCT in this report hardly showed the calcifications at the central portion of the maxillary sinus. The opacification in the maxillary sinus could be misdiagnosed as chronic maxillary sinusitis if the calcification of fungus ball was not simultaneously detected. The scan area of pre-operative CBCT needs to be enough to scan the paranasal sinus from top to bottom.

  14. Aspergillosis of the maxillary sinus. A clinical analysis of 24 cases. Comparision with 30 cases of non-fungal maxillary sinusitis

    The clinical and radiographic findings of 24 patients with aspergillosis of the maxillary sinus treated from 1989 through 2004 were compared with those of 30 patients with non-fungal maxillary sinusitis to clarify factors related to differential diagnosis. The subjects with aspergillosis were 9 men and 15 women aged 26 to 78 years (mean, 52 years). The patients with non-fungal sinusitis were 25 men and 5 women aged 23 to 73 years (mean, 46 years). The most common clinical finding at presentation was cheek pain, followed by nasal symptoms in the aspergillosis group. Nasal symptoms were more common in the non-fungal group than in the aspergillosis group. Thus, pain was more often associated with aspergillosis. Radiographically, diffuse radiopacity was observed in the maxillary sinus of all patients in both groups. In addition, dense antral radiopacities indicative of calcification were seen in a patient with aspergillosis. On X-ray-CT scans, bone thickening of antral walls (23 cases), sand-like high density areas (20 cases), extension of soft tissue masses to the nasal cavity (17 cases), foamy low density areas (13 cases), and bone destruction (6 cases) were seen in the aspergillosis group. These findings were rarely seen in the non-fungal group. All patients in both groups were treated by radical surgery of the maxillary sinus. The postoperative course was uncomplicated, and there was no recurrence as of 1 year postoperatively. In conclusion, the presence of pain, bone thickening of antral walls, sand-like high density areas, extension of soft tissue masses to the nasal cavity, foamy low density areas, and bone destruction on X-ray-CT scans were valuable for diagnosing aspergillosis of the maxillary sinus.

  15. Hemangioma of the Maxillary Sinus Presenting as a Mass: CT and MR Features

    Hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. We report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. Although computed tomography (CT) and magnetic resonance imaging (MRI) showed several enhancing areas within the tumor, the substantial bone erosion and remodeling made it difficult to differentiate this cavernous hemangioma from other expansile maxillary sinus lesions. We present the CT and MR findings of this lesion and discuss the differential diagnoses and potential therapeutic approaches

    João Felipe Bonatto Bruniera

    2015-01-01

    Full Text Available Oral rehabilitation with dental implants has become a routine treatment in contemporary dentistry. The displacement of dental implants into the sinus membrane, a complication related to the maxillary sinus, is one of the most common accidents reported in the literature. The treatment for this complication is the surgical removal of the implant. A 60-year-old woman with three dental implants displaced into the maxillary sinus (one implant displaced into the left maxillary sinus and two implants displaced into the right maxillary sinus underwent surgery for removal of the implants. The surgery to remove the implants was performed under local anesthesia through the Caldwell-Luc technique. The patient was subsequently administered antibiotic, anti-inflammatory, and analgesic drugs. The patient returned 7 days after the surgery for suture removal and is being regularly monitored to determine whether future rehabilitation of the edentulous area is necessary. In conclusion, surgical removal of the dental implant displaced into the maxillary sinus is the treatment of choice. This technique is appropriate because it allows the use of local anesthesia and provides direct visualization for the removal of the implants.

  17. Results of combined therapy for maxillary sinus squamous cell carcinoma

    The results of 54 cases of maxillary sinus squamous cell carcinoma treated between 1980 and 2002 were analyzed retrospectively. The T classification according to the 1997 Union Internationale Contre le Cancer (UICC) was as follows: 2 with stage T1, 29 with T3, and 23 with T4. Ten patients (18.5 %) had lymph node metastases at diagnosis. All patients underwent combined therapy including radiotherapy, surgery, and regional or systemic chemotherapy. Fifteen patients received hyperfractionated twice-daily radiotherapy (1.2 Gy or 1.5 Gy/fraction), and the remaining 39 patients received a conventional once-daily regimen (1.5-2 Gy/fraction). The 5-year overall survival and 5-year disease-free survival for all patients were 56.0% and 46.7%, respectively. The N classification was the only significant prognostic factor for 5-year disease-free survival by univariate analysis (favoring N=0, p=0.04). There were no significant differences in other prognostic factors including gender, T classification (T1-3 vs. T4), hyperfractionated radiotherapy (yes vs. no), total dose (biological effective dose (BED): 10 vs. ≥69 Gy10), and intra-arterial chemotherapy (yes vs. no). Although radiation-induced cataract was observed in 9 patients, no other severe late complications developed. (author)

  18. Case report Atypical clinic of foreign objects in the Maxillary Sinus ; Cluster-Type Headache

    2015-12-01

    Full Text Available Cluster-type headaches often seen in men, which might be a different intensity, around the eyes and in the temporal region, a type of primary headache that may continue approximately between 15 and 180 minutes. In the literature, a lot of reasons of cluster- type headache had been defined . Many systemic diseases may carry this symptom . Besides, belong the interest field of ear, nose and throat physician, it can bee seen in the paranasal sinus pathology. In the literature, Headache by the foreign bodies of maxillary sinus is considered extremely rare. İn this article, in the light of the literature, we present a patient refer to our clinic with symptoms of cluster headache, at paranazal sinüs CT scanning, in the maxillary sinus fungus ball was thought, that’s why caldwell-luc operation was performed and we extracted 11 pieces of glass from maxillary sinus.

  19. Comparison of panoramic radiography and cone beam computed tomography for assessing the relationship between the maxillary sinus floor and maxillary molars

    This study compared panoramic radiography and cone beam computed tomography (CBCT) for evaluating the relationship between the maxillary sinus floor and the roots of maxillary molars. Paired panoramic radiographs and CBCT images from 97 subjects were analysed. This analysis classified 388 maxillary molars according to their relationship to the maxillary sinus floor on panoramic radiograph and CBCT. Correlations between these two radiographic techniques were examined. Maxillary molar roots that were separate from the sinus floor showed the same classification in 100% of the cases when using these two imaging techniques. The corresponding percentage for such roots that were in contact with the sinus floor was 75%. When roots overlapped the maxillary sinus floor on panoramic radiographs, only 26.4% of maxillary first molars and 60.0% of second molars showed protrusion of roots into the sinus with CBCT. The results of the study suggest that roots projecting into the sinus on panoramic radiographs require a three-dimensional image in order to analyze the proximity of their apex to the sinus floor.

  20. The ethmoido-maxillary plate and paranasal sinuses. A study by HRCT

    The ethmoido-maxillary plate is a thin layer of bone separating the maxillary sinus from the ethmoidal cells or sphenoidal sinus. The plate was studied using axial HRCT images obtained from various otological lesions. One hundred forty-one adults were included in this study. The ethmoido-maxillary plate was first classified into four groups of configurations, namely, straight or near-straight, anterior-concave, posterior-concave and ant. and post. concave forms. The incidences of these forms were 55%, 23%, 13%, and 9%, respectively. A symmetrical configuration between the two sides was seen in 50%. The numbers of ethmoidal cells and/or sphenoidal sinus in contact with the plate and their incidences were 2 cells (47%), 3 cells (30%), 1 cell (15%), 4 cells (5%), and 5 cells (1%). The straight form showed lower numbers of cells than the other forms. The sphenoidal sinus and the maxillary sinus were in direct contact with each other at the ethmoido-maxillary plate in 19% of cases. (author)

  1. Evaluation of the maxillary sinus and adjacent structures on the orthopantomograph to the head positions

    The purpose of this study was to evaluate the utilization of the orthopantomogrph as a diagnostic aid to observe maxillary sinus and adjacent structures. For achieving this goal, the lead plates were attached to the five walls of the maxillary sinus of a human dry skull. The dry skull was placed in fourteen different positions ; standard, 20 mm forward, 20 mm backward, 10 degree upward, 10 degree downward, 20 mm lateral, forward and upward, forward and lateral, backward and upward, backward and downward, backward and lateral, upward and lateral, downward and lateral position. The obtained results were as follows: 1. The image of the medial wall was observed very differently according to the head positions. 2. The image of the anterior wall was observed at medial third to half of the maxillary sinus in each head position. 3. The image of the posterior wall was always observed at lateral third of the maxillary sinus in all head positions and more obviously in the downward-lateral position. 4. The image of the superior wall was observed at the inferior third to half of the orbit in each head position. 5. The image of the inferior wall was always observed at the inferior third of maxillary sinus in all head positions and observed more obviously in the standard and downward-lateral positions. 6. The image of the zygomatic process, zygomatic arch and zygomaticotemporal suture were observed very well in the downward-lateral position.

  2. Inflammatory myofibroblastic tumour of the maxillary sinus: CT and MRI findings

    Aim: To characterize the computed tomography (CT) and magnetic resonance imaging (MRI) findings of inflammatory myofibroblastic tumours (IMTs) of the maxillary sinus. Materials and methods: The imaging findings of eight patients with IMTs of the maxillary sinus were reviewed retrospectively. Of the eight patients, four patients underwent unenhanced and contrast-enhanced CT, and one patient underwent unenhanced CT only; three patients underwent unenhanced and contrast-enhanced MRI. Results: Five cases of IMTs occurred in the left maxillary sinus, while three cases were right-sided. Four cases occupied the entire sinus, and the other four cases only partially occupied the sinus. Unenhanced CT images showed heterogeneous masses in four cases and a homogeneous mass in one case. One of the tumours showed some areas of calcification. T1-weighted MRI images showed isointense lesions. T2-weighted images showed mixed isointense and mild hyperintense lesions. All cases showed bone destruction and had infiltrated into the nasal fossa, orbit, infratemporal fossa, and other adjacent tissues. Seven cases showed mild to moderate heterogeneous enhancement on contrast-enhanced CT or T1-weighted MRI images. Conclusion: IMTs of the maxillary sinus can be characterized as a soft-tissue mass with bony destruction and infiltration of the adjacent tissues, with mild to moderate enhancement after the injection of contrast medium. CT and MRI can help to diagnose IMTs, determine the extent of the lesion and its relationship with adjacent tissues, and thus facilitate the prediction of surgical resectability.

    2012-04-15

    The airflow and gas exchange behaviors of the human maxillary sinus were quantified to better understand the effect of an accessory ostium (AO). An anatomically correct numerical domain was constructed using CT data from a male patient with mild nasal obstruction. For the purpose of comparison, a numerical model without an AO was also generated by artificially removing the AO from the original model using CAD software. A steady-flow field through the nasal cavity was simulated using ANSYS-FLUENT v13.0 with a target flow rate of 250 ml/s. The Volume of Fluid (VOF) method was used to investigate the concentration field of nitric oxide (NO) initially filled in the maxillary sinus. The simulation results showed that a transit flow through the maxillary sinus developed in the presence of an AO. As the flow entered the sinus through either a natural or accessory ostium from the middle meatus, the velocity was significantly reduced to a local maximum of approximately 0.034 m/s inside the sinus. This by-pass flow rate through the sinus of 2.186×10(-1) to 3.591×10(-1) ml/s was a small fraction of the total flow rate inhaled from the nostril, but it effectively changed the local flow topology and led to a larger reduction in NO concentration in the maxillary sinus. This more rapid reduction in NO concentration was due to enhanced ventilation activity afforded by convective transport of the transit stream through the flow path connecting the natural ostium and the AO. The inspiration and expiration phases were qualitatively similar in flow pattern except for the flow direction in the maxillary sinus, suggesting that the AO plays a similar physiological role during both inspiration and expiration in terms of ventilation.

In the types of antral floor, there was a tendency to increase the separating type with age.

  5. Forensic importance of maxillary sinus in gender determination: A morphometric analysis from Western Uttar Pradesh, India

    Ruhi Sidhu

    2014-01-01

    Full Text Available Background: The study of anthropometric characteristics is of fundamental importance to solve problems related to identification. Craniometrical features are included among these characteristics, which are closely connected to forensic dentistry. Radiography is used in forensic for the identification of humans especially in cases where the body is decomposed, fragmented, or burned. Radiology can assist in giving accurate dimensions for which certain formulae can be applied to determine the gender. It has been reported that maxillary sinuses remain intact, although the skull and other bones may be badly disfigured in victims who are incinerated and therefore, that maxillary sinuses can be used for identification. Aim: This study has been carried out to check the accuracy and reliability of maxillary sinus in gender determination using morphometric parameters. Materials and Methods: Lateral cephalogram of 50 subjects (25 males and 25 females were taken and morphometric parameters of maxillary sinus were analyzed using AutoCAD 2010 software (Autodesk, Inc.. Results: The mean area and perimeter of maxillary sinus in males was 1.7261 cm 2 and 5.2885 cm whereas, the mean area and perimeter in females was 1.3424 cm 2 and 4.3901 cm. In-group centroids if someone′s discriminant function (DF score is close to 0.838 then the subject are supposed to be male. Whereas, those having DF score closer to −0.838 are supposed to be females. DF analysis showed that, 76% of the original grouped cases were correctly classified. Hence, the overall sensitivity and specificity was found to be 80% and 72%. Conclusion: It can be concluded that morphometric analysis (area and perimeter of maxillary sinus using AutoCAD 2010 software can assist in gender determination.

    Jalali, Elnaz; Al-Salman, Wesam; Jambhekar, Shantanu; Katechia, Bina; Almas, Khalid

    2016-01-01

    Purpose Sinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT). Materials and Methods Seventy-two sinuses from 36 random preoperative CBCT scans referred for implant therapy were retrospectively evaluated for the number, prevalence, and direction of bony septations and presence of pathology. Width of the sinus was also measured at 2 mm, 5 mm, and 10 mm from the sinus floor to account for the amount of bone available for implant placement. Results Maxillary sinus septa were found in 59.7%. Presence of a single septum was noted in 20 sinuses (27.7%), followed by two septa in 17 sinuses. The most common direction of the septum was the transverse direction. Retention pseudocyst and mucosal thickening were the most commonly seen abnormality/pathology. Conclusion Based on the high prevalence of septa and sinus pathology in this sample, a preoperative CBCT scan might be helpful in minimizing complications during sinus augmentation procedures for dental implant therapy.

    Takeshi Kusunoki

    2012-01-01

    Full Text Available We report a case of a neuroendocrine carcinoma arising in a wound of the postoperative maxillary sinus that was difficult to distinguish from a postoperative maxillary cyst. The patient was a 65-year-old Japanese woman who complained of left exophthalmos with cheek swelling and eye movement disorders. In past history, she had, 40 years previously undergone operation on the bilateral maxillary sinus by Caldwell-Luc’s method. In a preoperative computed tomography, a mass occupied the left maxillary sinus showing irregular densities with destruction of the posterior bone walls and invasion into the left orbital. Both TI and T2 weighted magnetic resonance imaging showed low intensities and unevenness in the mass. We performed a biopsy of the maxillary tumor according to Caldwell-Luc’s method. Histological examination diagnosed neuroendocrine carcinoma. Radiation therapy (total 66Gy resulted in partial response for this tumor. However, sinonasal neuroendocrine carcinoma has been identified as highly aggressive, with a high probability of recurrence and metastasis.

    Full Text Available Introduction: Biological matrix has received special attention in recent medical and biological researches. Cells of tissue are supported by extracellular matrix (ECM. Extracellular matrix is used as a scaffold for morphogenesis, proliferation, migration, and differentiation in tissue engineering. Extracellular matrix of natural tissues can be used as a scaffold for reconstructing biological tissues in tissue engineering. Human maxillary sinus membrane consists of cells and ECM which contain collagen, elastin, and proteoglycans. Collagen can be used as a natural scaffold via high level of biocompatibility. Materials & Methods: In this study, Human maxillary sinus membrane were decellularized by two techniques , physical method (liquid nitrogen and chemical procedures via increment concentration of sodium dodecyl sulfate (SDS in three groups. The samples were fixed with Bouin's fixator, and then were stained with Hematoxylin & Eosin. decellularised Human maxillary sinus membrane was evaluated with scanning electrone microscope.Results: Histological evaluation of decellularized scaffolds revealed that cells of the schneiderian membrane tissues were completely removed via concentration of 1% of SDS. Scanning Electrone Microscope (SEM (Leo-VP1450, Germany of the scaffolds indicated that collagen fibers of connective tissue remained intact. In 0.5 and 0.1% concentrations of SDS, few cells were observed at peripheral of ECM, so decellularization process was not complete. Conclusion: According to the results, scaffolds prepared from Human Maxillary Sinus Membrane could be used as a suitable scaffold for In vitro investigation and reconstruction and tissue engineering.

    Herein, we report a case of drug-induced Stevens Johnson syndrome. (SJS). A 56-year old female visited our hospital complaining of right cheek pain. Local examination revealed that the right ostium of the maxillary sinus was open and that the maxillary sinus mucosa was invaded by tumor. Biopsy revealed a histopathological diagnosis of squamous cell carcinoma. We therefore diagnosed the patient as a case of maxillary sinus carcinoma (T3N0M0) based on the CT, MRI and FDG-PET findings. During chemoradiotherapy for maxillary sinus cancer, the patient developed oral mucosal inflammation of progressively worsening severity; we initially thought that the symptom was a side effect of the treatment; however, several days later, skin lesions appeared throughout the body. We consulted a dermatologist, who suspected SJS. The patient was initiated on high-dose steroid therapy (steroid pulse therapy), and the symptoms improved. Because of SJS is a fatal drug eruption, early diagnosis and prompt treatment are important. In patients receiving chemoradiotherapy showing severe oral mucosal inflammation outside the irradiation area or oral mucosal inflammation associated with skin lesions throughout the body, it is necessary to bear in mind the possibility of SJS.

  18. Two cases with radiation-induced cancers after radiation therapy for cancer of the maxillary sinus

    We experienced 2 patients with malignant non-epithelial tumors that developed following an incubation stage of 10 years or more after radiation therapy for cancer of the maxillary sinus. In Patient 1, the primary cancer was unclear, but it was speculated that this patient had been treated for cancer of the maxillary sinus. In patient 2, cancer of the maxillary sinus had been treated in our hospital. In patient 1, the secondary cancer was a malignant histiocytoma of the parapharyngeal space. In patient 2, the secondary cancer was a spindle cell sarcoma in the maxillary sinus. According to the classification of the probability of radiation-induced cancer after treatment for malignant tumors, the probability was evaluated as A in Patient 2, and B or higher in Patient 1. In the two patients, radiation-induced cancer was strongly suggested. For treatment, extended surgery was indicated, as a rule. In Patient 1, radical neck dissection was performed. In patient 2, tumorectomy was performed several times. Concerning the prognosis, Patient 1 is alive without cancer, but Patient 2 died of intracranial invasion by tumor. The invasion of the tumor and histological type may have influenced the prognosis. The incidence of radiation-induced cancer is considered to be 1% or less. However, radiation therapy-related late disorder must be considered. (author)

    Full Text Available Purpose. The aim of this paper is to report a case in which the cone beam computed tomography (CBCT was important for the confirmation of the presence of maxillary sinus septum and, therefore, the absence of a suspected pathologic process. Case Description. A 27-year-old male patient was referred for the assessment of a panoramic radiograph displaying a radiolucent area with radiopaque border located in the apical region of the left upper premolars. The provisional diagnosis was either anatomical variation of the maxillary sinuses or a bony lesion. Conclusion. The CBCT was important for an accurate assessment and further confirmation of the presence of maxillary septum, avoiding unnecessary surgical explorations.

  20. Maxillary sinusitis as a differential diagnosis in temporomandibular joint pain-dysfunction syndrome.

    Rihani, A

    1985-01-01

    Maxillary sinusitis may be diagnosed incorrectly as TMJ pain-dysfunction syndrome because of a similarity of signs and symptoms. Both conditions can manifest with headache, facial pain radiating to the ear and the maxillary teeth, preauricular pain, and pain in the buccal vestibule posterior and superior to the maxillary tuberosity. It can be concluded that (1) more consideration should be given to sinus disturbances as a differential diagnosis in TMJ pain-dysfunction syndrome, (2) it may be preferable to refer some patients with TMJ pain to a medical center where specialists in dentistry, otolaryngology, neurology, rheumatology, and psychiatry can evaluate the patient, and (3) TMJ pain-dysfunction syndrome should be evaluated and treated by a dentist experienced in management of this disorder.

  1. Usefulness of Panoramic Radiography in the Detection of Maxillary Sinus Pathosis

    to evaluate the usefulness of the panoramic radiography, generally used in dental clinic, for the detection of the maxillary sinus pathosis due to the inflammation and tumor, through the comparison with CT findings as the absolute standard. 150 maxillary sinuses of 75 patients with or without particular signs and symptoms and showing soft tissue lesions or destruction of maxillary sinus walls in at least one sinus in CT, were selected as subject samples, and the panoramic radiography of the same patients were interpretated by 3 dental radiologists and 3 non dental radiologist given no previous information. Using the CT findings as the absolute standard, the diagnostic ability of panoraimc radiography in the mucosal thickening, maxillary sinus haziness, inferior wall destruction, medial wall destruction, posterolateral wall destruction and the superior wall destruction was evaluated using the ROC curve and the difference between dental radiologist group and non dental radiologist group was also evaluated. 1. When dental radiologist group interpretated the destruction of inferior wall and posterolateral wall, the kappa value which shows interobserver's coincidence was above 0.75.2. The diagnostic ability according to site of interpretation was the highest when the inferior wall was interpretated in both observer groups and there was a statistically significant difference between the dental radiologist group and non dental radiologist group in interpretating the mucosal thickening, haziness, destruction of the inferior and medial wall (p<0.05).3. The diagnostic ability in detecting the destruction of the sinus walls was better than in soft tissue lesions in both groups and between the groups there was a statistically significant difference (p<0.05). When detecting the destruction of inferior and posterolateral wall of the maxillary sinus there was coincident with that of CT findings, and so it is considered that diagnostic ability of panoramic radiography is high in

  2. Clinical study on the observation of unilateral shadows in the maxillary sinus

    In the everyday examination of patients exhibiting a unilateral shadow in the maxillary sinus upon imaging, the differentiation of chronic sinusitis from other diseases, including malignant tumors, is extremely important. A unilateral shadow in the maxillary sinus was detected on scout films and a subsequent CT examination of the sinus was performed in 108 patients who visited our department between January 1994 and December 1998. Bone destruction was suspected after scout films were taken in 2 patients with malignant tumors. These 2 patients account for only a small percentage of the total patient population, but account for as much as 50% of the patients with malignant tumors. In cases of malignant tumors, the CT images suggesting bone destruction agreed with operative findings. CT seems to be a useful tool for evaluating the condition of the bone. When the density of scout films and CT images were compared, no significant difference was detected, suggesting that scout films can be used for the screening of malignant tumors. The density was (+++) in both the scout films and the CT images of the 2 patients with malignant tumors. Finally, we present a flow chart for the diagnosis of unilateral maxillary sinus shadows that has been recently adopted as the basic protocol used in our department. (author)

    Objectives Healing processes of the nose and paranasal sinuses are quite complex, and poorly understood. In this study, we aimed to compare the effect of mucosal autologous grafts on the degenerated rabbit maxillary sinus mucosa with spontaneous wound healing. It is hypothesized that mucosal grafts will enhance ciliogenesis and improve the morphology of regenerated cilia. Methods Ten female New Zealand rabbits were included in the study. They underwent external maxillary sinus surgery through a transcutaneous approach. A total of 20 maxillary sinuses were randomly divided into 2 groups: ‘spontaneous healing group’ and ‘autologous graft group.’ The animals were sacrificed at the 14th day after the surgery. Scanning electron microscope (SEM), and light microscope were used for the evaluation. Results Cellular composition of the graft group is better than the spontaneous healing group. The graft group had larger areas covered with ciliary epithelium than the spontaneous healing group, and the mean length of the cilias were also longer. Additionally, there were wider cilia with abnormal morphology areas in the spontaneous healing group. Conclusion In our opinion, covering of the denuded areas with a graft improves re-epithelization, and may prevent the early complications after sinus surgeries. PMID:26976026

  4. Features of inflammatory pseudotumor in the maxillary sinus on CT and MRI

    Objective: To explore the features of inflammatory pseudotumor in the maxillary sinus on CT and MRI. Methods: The CT and MRI data of 8 patients with histology-proven inflammatory pseudotumor in the maxillary sinus were retrospectively analyzed. All 8 patients underwent CT scans and 7 of them also underwent MRI examinations. In addition, the time-intensity curve (TIC) of dynamic contrast-enhanced (DCE)MR imaging were analyzed in 3 patients. Results: Two cases had lesions in the left maxillary sinus, while the others showed lesions in the right maxillary sinus. All the lesions showed irregular shape with well-defined margins in 5 cases and hazy margins in 3 cases. The mean maximum diameter of the lesions was 51 mm (ranged from 29 mm to 72 mm). On non-enhanced CT, the lesions were isodense to gray matter in 6 and slightly hypodense in 2 patients. Only 2 patients had post-contrast CT with moderate enhancement of their lesions. The lesions caused adjacent bony absorption and destruction with residual bony sclerosis. On MR T1WI, inflammatory pseudotumor showed hypointense in 2 patients and isointense in and isointense in 1 patients. Inflammatory pseudotumor showed heterogeneously slight contrast enhancement in 2 cases and moderate enhancement in 5 cases. The TIC showed a steady enhancement pattern in 4, orbit in 4, and cheek in 3 cases. Six patients underwent follow-up for 2-5 years after surgery and 2 of them were found to have recurrence. In comparison to CT, MRI was proved to show the extent of the lesions more clearly. Conclusions Bony destruction with sclerosis and hypointense signal on MR T2WI are typical manifestations of inflammatory pseudotumor in the maxillary sinus. Combined CT and MRI can provide clinicians with more comprehensive information for the diagnosis, therapy, and follow-up of these lesions. (authors)

  5. Association Between the Lateral Wall Thickness of the Maxillary Sinus and the Dental Status: Cone Beam Computed Tomography Evaluation

    Assessment of the lateral wall thickness of the maxillary sinus is very important in decision making for many surgical interventions. The association between the thickness of the lateral wall of the maxillary sinus and the dental status is not well identified. To compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. In a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary sinus,one centimeter above the sinus floor in the second premolar (P2), first molar (M1) and second molar (M2) areas was determined by cone beam computed tomography scans(CBCTs) and a digital ruler in Romexis F software (Planmeca Romexis 2.4.2.R) and it was compared with values measured in fifty dentated individuals. Three way analysis of variance was applied for comparison after confirmation of the normal distribution of data. The mean of the wall thickness in each of these points was lower in patients with edentulous spaces; however it was not significant. There was no association between gender and the thickness of the lateral wall of the maxillary sinus, but location was associated with different thicknesses. The differences in the thickness based on the location and dental status necessitates assessment of the wall thickness of the maxillary sinus in addition to the current evaluation of bone thickness between the sinus floor and the edentulous crest before maxillary sinus surgery

    Efficient management of chronic sinusitis remains a great challenge for primary care physicians. Unlike ENT specialists using Computed Tomography scans, they lack an affordable and safe method to accurately screen and monitor sinus diseases in primary care settings. Lack of evidence-based sinusitis management leads to frequent under-treatments and unnecessary over-treatments (i.e. antibiotics). Previously, we reported low-cost optical imaging designs for oral illumination and facial optical imaging setup. It exploits the sensitivity of NIR transmission intensity and their unique patterns to the sinus structures and presence of fluid/mucous-buildup within the sinus cavities. Using the improved NIR system, we have obtained NIR sinus images of 45 subjects with varying degrees of sinusitis symptoms. We made diagnoses of these patients based on two types of evidence: symptoms alone or NIR images along. These diagnostic results were then compared to the gold standard diagnosis using computed tomography through sensitivity and specificity analysis. Our results indicate that diagnosis of mere presence of sinusitis that is, distinguishing between healthy individuals vs. diseased individuals did not improve much when using NIR imaging compared to the diagnosis based on symptoms alone (69% in sensitivity, 75% specificity). However, use of NIR imaging improved the differential diagnosis between mild and severe diseases significantly as the sensitivity improved from 75% for using diagnosis based on symptoms alone up to 95% for using diagnosis based on NIR images. Reported results demonstrate great promise for using NIR imaging system for management of chronic sinusitis patients in primary care settings without resorting to CT.

  7. An assessment of maxillary sinus and alveolar bone in cross-sectional linear tomogram of panorama

    To evaluate the precision of measurements taken of dental implants in bucco-lingually sectioned views of the maxilla by linear tomograms of the panorama and to assess the visibility of the inferior wall of the maxillary sinus. Eighty sites prepared with implants of gutta percha cone in the sockets of the upper premolars and molars of 10 dry skulls were radiographically examined using linear tomograms of panorama, and scanned coronally and axially by computed tomography. The differences in mm between the measurements in bucco-lingually sectioned images of maxillary alveolar bone and the true length and width of the implanted gutta percha cones were compared as mean values (mean) and standard deviation (SD) for each radiographic technique. Linear tomography of panorama was compared with computed tomography for visualization of the relationship between the inferior wall of maxillary sinus and the end of each implant. The deviations between the actual implant length and the measured values taken from the linear tomograms (0.44 ± 0.39 mm) was significantly less than the measured values from the multiplanar reconstructed images of the axially scanned computed tomogram (1.21 ± 0.90 mm). There was statistically significant difference (p<0.05) between two techniques in the differences between the measurements and true implant length. The relationship of the inferior border of maxillary sinus with end of implant was worse identified with the linear tomogram of panorama (68%) than the multiplanar reconstructed image of axially scanned computed tomogram (99%). We could not find any differences in the accuracy of length measurement between the linear tomogram of panorama and computed tomogram, but computed tomogram allowed for a better visualization of the inferior wall of the maxillary sinus than the linear tomogram.

    2012-08-01

    Full Text Available Abstract Background Although cone beam computed tomography (CBCT images of the maxillofacial region allow the inspection of the entire volume of the maxillary sinus (MS, identifying anatomic variations and abnormalities in the image volume, this is frequently neglected by oral radiologists when interpreting images of areas at a distance from the dentoalveolar region, such as the full anatomical aspect of the MS. The aim of this study was to investigate maxillary sinus abnormalities in asymptomatic patients by using CBCT. Methods 1113 CBCT were evaluated by two examiners and identification of abnormalities, the presence of periapical lesions and proximity to the lower sinus wall were recorded. Data were analyzed using descriptive statistics, chi-square tests and Kappa statistics. Results Abnormalities were diagnosed in 68.2% of cases (kappa = 0.83. There was a significant difference between genders (p Conclusions Abnormalities in maxillary sinus emphasizes how important it is for the dentomaxillofacial radiologist to undertake an interpretation of the whole volume of CBCT images.

  9. Non-intrusive optical study of gas and its exchange in human maxillary sinuses

    Persson, L.; Andersson, M.; Svensson, T.; Cassel-Engquist, M.; Svanberg, K.; Svanberg, S.

    2007-07-01

    We demonstrate a novel non-intrusive technique based on tunable diode laser absorption spectroscopy to investigate human maxillary sinuses in vivo. The technique relies on the fact that free gases have much sharper absorption features (typical a few GHz) than the surrounding tissue. Molecular oxygen was detected at 760 nm. Volunteers have been investigated by injecting near-infrared light fibre-optically in contact with the palate inside the mouth. The multiply scattered light was detected externally by a handheld probe on and around the cheek bone. A significant signal difference in oxygen imprint was observed when comparing volunteers with widely different anamnesis regarding maxillary sinus status. Control measurements through the hand and through the cheek below the cheekbone were also performed to investigate any possible oxygen offset in the setup. These provided a consistently non-detectable signal level. The passages between the nasal cavity and the maxillary sinuses were also non-intrusively optically studied, to the best of our knowledge for the first time. These measurements provide information on the channel conductivity which may prove useful in facial sinus diagnostics. The results suggest that a clinical trial together with an ear-nose-throat (ENT) clinic should be carried out to investigate the clinical use of the new technique.

  10. A comparison of Scanora radiography with Waters' and panoramic views for the detection of mucosal thickening of maxillary sinus

    The purpose of this study was to compare the diagnostic performance of Waters' and panoramic view; maxillary sinus posteroanterior and lateral scanography of Scanora for mucosal thickening of maxillary sinus as well as to identify the utility of Scanora for the detection of maxillary sinus disease. The assessment was done at 66 maxillary sinuses in 45 patients and the results were as follows: 1. Estimation of presence or absence of mucosal thickening. The sensitivity, specificity, and positive and negative predictive value of maxillary sinus posteroanterior and lateral scanography were 0.865, 0.860, 0.921, and 0.805 respectively and slightly higher than those of Waters' and panoramic views, which were 0.832, 0.835, 0.903, and 0.728 respectively. However, paired t-test showed no significant differences in the diagnostic performance of the two pairs of imaging modalities. 2. Estimation of the types of mucosal thickening. The diagnostic accuracy for type I, II, III was 75.3% on Waters' and panoramic view; 77.9% on maxillary sinus posteroanterior and lateral scanography. It was higher on the latter, but showed no significant differences from that on the former. 3. Reliability of interpretation. In intraobserver and interobserver agreement, both overall rates of agreement and kappa-value were slightly higher on maxillary sinus posteroanterior and lateral scanography than on Waters' and panoramic views. There was no significant differences between the two pairs of imaging modalities. These results suggested that scanogram is a useful diagnostic radiography as well as Waters' and panoramic view for detection of maxillary sinusitis.

  12. Measurement of maxillary sinus volume and available alveolar bone height using computed tomography

    To aid in determining the volume of graft bone required before a maxillary sinus lift procedure and compare the alveolar bone height measurements taken by panoramic radiographs to those by CT images. Data obtained by both panoramic radiographs and CT examination of 25 patients were used in this study. Maxillary sinus volumes from the antral floor to heights of 5 mm, 10 mm, 15 mm, and 20 mm , were calculated. Alveolar bone height was measured on the panoramic images at each maxillary tooth site and corrected by magnification rate (PBH). Available bone height (ABH) and full bone height (FBH) was measured on reconstructed CT images. PBH was compared with ABH and FBH at the maxillary incisors, canines, premolars, and molars. Volumes of the inferior portion of the sinuses were 0.55 ± 0.41 cm3 for 5 mm lifts, 2.11 ± 0.68 cm3 for 10 mm, 4.26 ± 1.32 cm3 for 15 mm, 6.95 ± 2.01 cm3 for 20 mm. For the alveolar bone measurement, measurements by panoramic images were longer than available bone heights determined by CT images at the incisor and canine areas, and shorter than full bone heights on CT images at incisor, premolar, and molar areas (p3 or more is required for a 5 mm - lift, 2.79 cm3 or more for a 10 mm - lift, 5.58 cm3 or more for a 15 mm - lift, and 8.96 cm3 or more for a 20 mm - lift. Maxillary implant length determined using panoramic radiograph alone could result in underestimation or overestimation, according to the site involved.

    2016-01-01

    Full Text Available Purpose: Identification of human body or remains after death is a forensic procedure, which is difficult to perform and is mandatory by law and in compliance with social norms. Sexing the recovered human remains is an integral part of the identification process. Maxillary sinus can be used for gender determination as it remains intact even when the skull and other bones may be badly damaged in casualties where the body is incinerated. Computed tomography (CT provides an excellent method for examining maxillary sinuses. Materials and Methods: CT images were used to measure the mediolateral, superoinferior, and anteroposterior dimensions and the volume of the maxillary sinuses in 30 patients (15 males and 15 females to investigate whether these parameters could be used to determine the gender of an individual for forensic identification. The t-test for independent samples was used to compare these values in males and females and the data were subjected to discriminative analysis using SPSS software. Results: Our method was able to predict the gender with an accuracy of 80.0% in males and 86.7% in females, with an overall accuracy rate of 83.3%. Conclusion: The accuracy rate in this study was comparable, if not higher than many other methods that have been used to predict the gender of an individual from skeletal remains. The length, width, height, and volume of the maxillary sinuses together with other bones could be used for gender determination with a fair degree of accuracy when the whole skeleton is not available.

    Full Text Available Background: The optimal treatment of maxillary sinus carcinoma remains to be defined and there is a paucity of Indian studies on the subject. Aims: To present experience of management of squamous cell carcinoma of the maxillary sinus treated with curative intent at a single institution. Settings and Design:Retrospective study of patients with squamous cell carcinoma of the maxillary sinus who presented between 1994 to 1999. materials and Methods:The records of 73 patients with squamous cell carcinoma of the maxillary sinus were analyzed. Sixty-two patients were evaluable. Forty patients (65% were treated with surgery followed by postoperative radiotherapy, five patients (8% were treated with radiotherapy alone, five patients (8% were treated with surgery alone; 12 patients (19% received chemotherapy. Statistical analysis used: Statistical analysis was done using Kaplan-Meier method. Results: The majority of patients presented with locally advanced disease (52, 84%; nodal involvement was observed in five patients (8%. The most common site of recurrence was at the primary site, which was observed in 28 patients (45% and regional failures occurred in 10 (16%. The 3 and 5-year overall survival was 38% and 35% and the disease free survival was 29% and 26% respectively. The 5-year overall survival after surgery and postoperative radiotherapy was 42%. Conclusions:The majority of patients present with advanced disease resulting in poor outcomes to conventional treatment modalities. Locoregional tumor progression remains a significant pattern of failure. New approaches such as neoadjuvant or concomitant chemoradiotherapy with aggressive surgery need to be considered and evaluated in prospective studies.

  19. Radiological studies on carcinoma of the maxillary sinus with special emphasis on computed tomography

    The purpose of this study was to compare the conventional X-ray images with computed tomography(CT) as the new radiological imaging on the diagnostic accuracy of carcinoma of the maxillary sinus. Forty five patients with carcinoma of the maxillary sinus were analysed by Waters' view, conventional tomography and CT. CT scans were performed in transverse(CT-T)and coronal(CT-C) directions by GE CT/T 8800 machine. The results obtained were as follows: 1. CT was superior to Waters' view and conventional tomography in this disease for evaluating the involvement of the maxillary walls and adjacent bony structures. 2. Thirty nine of 45 cases revealed the bony changes of postero-lateral wall in CT. The grading of this bony changes were as follows. a, completely disappeared pattern. b, granular pattern. c, expansive and disrupted pattern. d, discontinous pattern. e, expansive and erosive pattern. 3. CT was also useful for detection of the tumor extension to surrounding structures, especially on pterygoid muscles, orbit and brain. 4. The mean value of CT numbers on carcinoma in the antrum, sinusitis and lateral pterygoid muscles were 47.07 +- 10.70,30.20 +- 12.04 and 54.19 +- 11.17, respectively. The values among above three locations showed significant difference(P < 0.01). 5. Clinically, the frequency of the involvement of lateral pterygoid muscles in CT images was correlated to the duration of the illness. (author)

  20. Mucoceles in post-operative maxillary sinuses: CT and MR findings

    This study describes the CT and MR findings of mucoceles occurred in the post-operative maxillary sinuses. CT and/or MR of 19 maxillary mucoceles in 16 patients who had been operated by Caldwell-Luc procedure were reviewed. CT scans were performed after contrast enhancement in axial and coronal planes with 5mm thickness. Three cases were studied with a 2.0 T or 0.5 T MRI, which demonstrated multi-compartment lesions. The lesions were bilateral in 3 cases. Compartmentalization of the antral cavity was seen in 7 out of 19 involved sinuses. Surgical bone defect of the anterior wall was the most frequent route of extension (11 cases) and extension into the infratemporal fossa with erosion of posterolateral wall was seen in 7 lesions. In 6 cases, the lesion involved orbit. The expansile and erosive bone changes were localized in every case. In one case with multi-compartment lesion, both T1-and T2-weighted MR images showed different signal intensities in each compartment which represented different protein concentration. Post-operative maxillary mucocele showed CT findings of localized erosion and bulging most frequently at the anterior wall in which the bone windows were made during he previous surgery. Post-operative compartmentalization of maxillary antrum may cause eccentric expansion of mucocele and each compartment may show different signal intensities on MR

    Biočanin Vladimir

    2015-01-01

    Full Text Available Introduction. Therapeutic approach to jaw cysts may depend on their dimensions and localization. Enucleation of cystic lesion is not always preferable in the first act, especially if large cysts are in close proximity to important anatomical structures. The aim of this paper was to present the outcome of the treatment protocol comprising preoperative decompression and subsequent enucleation of a large maxillary cyst. Case report. A 21-year-old male patient with large asymptomatic radicular cyst in the right maxillary sinus was presented to our clinic. Cone-beam computed tomography (CBCT showed a large cyst, which perforated the right anterior maxillary wall by 1.5 cm, and was in the intimate contact with the orbital floor. Surgical treatment of the cystic lesion comprised: preoperative decompression with biopsy in the first act and enucleation, performed under general anesthesia, 6 months after the observation period. Conclusion. Decompression with subsequent enucleation proved to be effective treatment of large radicular cyst in maxillary sinus with low-morbidity.

    In this study, we examined the effect of uncinectomy on the alteration in local airflows and on the resulting effect on gas exchange in the maxillary sinus, by using computational fluid dynamics in two nasal cavity models: one with a preserved uncinate process, and the other with the uncinate process removed virtually. Uncinectomy distinctively changed the local flow topology by triggering the formation of counter-rotating vortices in the ostiomeatal complex, except for the instants with relatively low airflow rate when the respiration phase changed, ultimately leading to a change in the velocity field inside the ostium and maxillary sinus. Despite a significant increase in the maximum air velocity through the maxillary ostium, ventilation was found to increase only slightly when the uncinate process was removed. Furthermore, the degree of maxillary sinus ventilation by inhaled air was comparable to that by exhaled air. This was true to both models and was independent of the presence of the uncinate process.

    2014-09-01

    Full Text Available Background. The feature of malignant tumours in maxillary sinus is a late appeal of patients (T3-T4, as a result of the absence of pain and minor clinical manifestations, it requires large amounts of surgical interventions and leads to disability. Objective. The article analyzes the morphological variants of maxillary sinus squamous cell carcinoma (SCC with their immunohistochemical characteristic. Methods. In the study we analyzed the original biopsy material from 37 patients with maxillary sinus cancer T3-4N0-1M0 (31 men and 6 women aged from 37 to 71 years with histologically confirmed diagnosis of SCC for 2010-2014. The primary monoclonal antibodies CK HMW (clone AE3, p63 (clone 4A4, р16INK4 (clone DCS 240 were used. Results. Analyzing the distribution of various forms of maxillary sinus SCC, it was found that the typical forms of SCC are found in most of cases, 29 of 37 (78.4%, compared with specific morphological forms that accounted for just 21.6%. Conclusions. Due to the expression of the marker CK HMW it was found that in typical forms of SCC and in some special morphological forms (spindle cell carcinoma and verrucous carcinoma with decreasing degree of squamous cell differentiation, the level of the expression of CK HMW also decreases (p<0,001, r = 0.861; p <0,001, r = 0,638. It is an indicator of poor prognosis, but aggressive behavior of basaloid SCC and adenosquamous carcinoma do not depend on the presence or absence of CK HMW. High expression of marker p63 (average level 92,5±3,67% is a key-point of verification of basaloid SCC. Lack of positive reaction with the marker of viral lesions p16INK4 in forms with keratinization confirms the idea of different etiologic factors and ways of carcinogenesis of typical forms of SCC.

    2010-01-01

    Full Text Available The objective of this study was to determine the prevalence of concha bullosa and nasal septal deviation and their potential relationships to maxillary sinusitis. 883 CT scans taken at Creighton University School of Dentistry from 2005 to 2008 were retrospectively reviewed for the presence of concha bullosa, nasal septal deviation, and maxillary sinusitis. 67.5% of patients exhibited pneumatization of at least one concha, 19.4% of patients had a deviated septum, and 50.0% had mucosal thickening consistent with maxillary sinusitis. 49.3% of patients who had concha bullosa also had evidence of maxillary sinusitis. Only 19.5% of patients with concha bullosa also had nasal septal deviation, whereas 19.7% of patients with sinusitis also presented with nasal septal deviation. Although concha bullosa is a common occurrence in the nasal cavity, there did not appear to be a statistically significant relationship between the presence of concha bullosa or nasal septal deviation and maxillary sinusitis.

    Dooley, Laura; Shah, Jatin

    2016-01-01

    Purpose of Review To discuss and review the role for elective treatment of the neck in maxillary squamous cell carcinoma. Improvements in survival have been seen due to improved local therapies and control, therefore the treatment of the neck has become a topic of debate. Recent findings The risk of occult metastases in neck nodes is higher for T 3-4 tumors. The rate of nodal relapse in the N0 neck without elective treatment is 8-15%. With elective irradiation the nodal relapse rate decreases. However, most nodal relapses are accompanied by local failure or distant disease. Local failure remains the most common site of failure and cause of death in this patient population. Summary Treatment failure occurs overall in 62% of all patients, with local recurrence by far the most common site of treatment failure which is rarely amenable to salvage therapy. Therefore elective neck irradiation is not routinely indicated in the clinically N0 neck; those who recur only in the neck can be surgically salvaged more than 50% of the time. PMID:25692625

  9. The experimental study of 32P-colloid perfusion therapy in the animal-models of chronic maxillary sinusitis

    Objective: To search for the mechanism of 32P-colloid perfusion therapy in the animal models of chronic maxillary sinusitis. Methods: 32P-colloid were injected into the male sheep maxillary sinuses of the animal-models of chronic maxillary sinusitis in different dosage group. The changes of bacteria and mucosael pathomorphology were observed by periodic germiculture and pathology in 1,3,6 months after injection. Results: After 32P-colloid perfusion therapy, the amounts of bacterial species and chronic phlogistic cells were remarkable reduced, and the structure of cilia cells did not change. The curable rate was 83.3% in 6 months. There were remarkable difference in groups. Conclusions: 32P-colloid was provided with antibiosis and reducing chronic phlogistic responses. The authors had found the optimal dose of 32P-colloid perfusion in the maxillary sinuses through the study. The curable rate of single dose of 32P-colloid perfusion in the maxillary sinuses was higher than other therapy, 32P-colloid perfusion was simple and convenient. There was high selectivity of 32P in the target organ, when there was no effect on other important organs through radiobiological measurement. (authors)

  10. Extensive complex odontoma in the maxillary sinus pushing 3rd molar near the orbital floor causing transient diplopia and chronic sinusitis: a rare presentation and surgical management.

    Gupta, Monika; Das, Debdutta

    2015-03-01

    Odontoma is a mixed odontogenic hamartoma involving both epithelial and mesenchymal tissues. If left untreated, it can lead to complications in certain conditions. Here is a rare presentation of an extensive complex odontoma in maxillary sinus pushing third molar near the orbital floor causing transient diplopia in upward gaze occasionally and chronic sinusitis. Although odontomata are not uncommon and are familiar to practitioners, but some aggressive cases may cause problematic sequelae. Even postoperative complications may result if oral surgeons are not aware of the potential pitfalls associated with the surgical removal of large maxillary antrum odontomata. This article reports a rare presentation which can be considered unique because when obstruction of sinus drainage is evident, serious complications such as orbital infections, epidural and subdural empyema, meningitis, cerebritis, cavernous sinus thrombosis, brain abscess and death can occur. It also addresses points and pitfalls concerning surgery to remove odontoma. PMID:25848139

  11. A radiographic study on the mucosal cyst of the maxillary sinus

    This study was performed to evaluate the role Waters' view and panoramic view for the interpretation of mucosal cyst of the maxillary sinus and to determine the radiographic features of that according to the sites and sizes. For this study, clinically 25 cases of mucosal cyst of the maxillary sinus were used, and experimentally with who dry skulls, rubber ball of 15 mm in diameter for marked radiopacity, and two jelly balls of 8 and 20 mm in diameter for the similar radiopacity to cyst were used. The 25 cases with 25 panoramic views and 15 Waters' views were first analyzed, and secondly, the radiographic features of artificial lesions attached to the each wall of the antrum on Waters' view and panoramic view were analyzed. The obtained results were as follows: At clinical analysis, 1. 4 cases of 13-14 mm, 4 cases of 15-19 mm, 14 cases of 20-25 mm, 3 cases of over 30 mm in diameter were found on panoramic views. And 24 cases of 25 cases showed no relationship with teeth, and only 1 case was associated with advanced periodontal disease. 2. The majority of mucosal cysts appeared to arise the posterior portion of the floor of the sinus and were superimposed with the inominate line of zygoma and the horizontally linear image of hard palate on panoramic view. 3. Only 2 cases of 15 cases were identified on both films.At experimental analysis, 4. On Waters' view, the images of the artificial lesion of the anterior portion and midportion of the floor of the sinus were lessened in diameter compared with the real size. On panoramic views, the images of the lesion were more radiolucent with lessened diameter than images on Waters' view. 5. The images of the lesion of the posterior wall and the posterior portion of the floor of sinus on panoramic view were well detected by the preedjucated group but not or poorly detected by the non-preeducated observer group. 6. On Waters' view, both observer groups recognized that the cystic images of the posterior portion of the floor of the

  13. Metastasis of hepatocellular carcinoma presented as a tumor of the maxillary sinus and retrobulbar tumor

    Kolarević Daniela

    2011-01-01

    Full Text Available Introduction. Hepatocellular carcinoma (HCC is the most frequent primary malignant tumor of the liver. It is usually seen in the 6th and 7th decades of life and chronic hepatitis B is the most frequent cause. Extrahepatic metastasis of HCC is an indicator of a poor prognosis and the most common sites are lungs, bones, lymph nodes, kidneys and adrenal glands. We reported a case of isolated metastasis in the right maxilla, which had been found initially, before the tumor in the liver was diagnosed. Case report. A 70-year-old man underwent dental surgery of the upper right molar. Prolonged bleeding control was difficult for up to two weeks, so the biopsy was performed. Histopathological analysis revealed a metastatic hepatocellular carcinoma. Computerized tomography (CT of the abdomen revealed a diffusely heterogeneous liver parenchyma with irregular borders and two foci of mass lesions. There were metastasis in the spleen and also two pathological retroperitoneal lymph nodes were detected, but no ascit, liver cirrhosis, cholestasis or portal vein thrombosis were seen. CT of the orbital and maxillary regions revealed a tumor mass in the right maxillary sinus, spreading to the alveolar sinus, nasal cavity and partially infratemporal space. A tumor mass was in the right orbit as well, infiltrating the surrounding bones and muscles. Clinically, there was proptosis of the right eye accompanied by amaurosis. The treatment started with chemotherapy based on 5-fluorouracil (sorafenib was not available. After three cycles, control CTs showed a stable disease in the liver, but progression in the right maxillary sinus and orbit. Enucleation of the right eye was performed and postoperative radiotherapy was planed. The patient deteriorated rapidly and died, about 6 months after the disease had been diagnosed. Conclusion. Extrahepatic metastasis of HCC represents a progressive phase of the disease with poor prognosis, so the main aim of the treatment should be

  14. Influence of postsurgical residual tumor volume on local control in radiotherapy for maxillary sinus cancer

    The aim was to study the influence of postsurgical gross residual tumor volume on local control of maxillary sinus cancer treated with radiotherapy combined with debulking surgery. Forty-three patients who underwent combined surgery and radiotherapy (50-72 Gy, median 60 Gy) for squamous cell carcinoma of the maxillary sinus were reviewed. Gross residual tumor volume (GRTV) after surgery was measured on computed tomograms obtained during the radiotherapy planning. Patients were classified according to GRTV as follows: group AA, GRTV=0 (microscopic residual, n=2); group A, GRTV 3 (n=24); group B, 10-40 cm3 (n=9); and group C, ≥40 cm3 (n=8). The relationship between local control and GRTV was analyzed using univariate and multivariate analysis. The 2-year local control rate for all patients was 62%. The differences in local control rates between groups AA, A and B were not significant (P<0.05), but the rate was significantly lower in group C than in the other groups (69% at 2 years vs 31% at 1 year, P<0.001). Multivariate analysis showed that GRTV (P=0.002) and histological differentiation (poorly differentiated histology was favorable, P=0.035) were independent prognostic factors and that intraarterial chemotherapy and administered total dose were not. Local control in groups A and B significantly depended on the total dose of radiotherapy, with 2-year control rates of patients receiving 50 Gy (n=6) and ≥60 Gy (n=27) of 17% vs 79%, respectively (P<0.001). Our data suggest that adequate, not complete, debulking associated with a total radiotherapy dose of ≥60 Gy can provide satisfactory local control for patients with squamous cell carcinoma of the maxillary sinus.

  16. Paranasal sinuses in children: size evaluation of maxillary, sphenoid, and frontal sinuses by magnetic resonance imaging and proposal of volume index percentile curves

    Our objective was to establish the age-related 3D size of maxillary, sphenoid, and frontal sinuses. A total of 179 magnetic resonance imaging (MRI) of children under 17 years (76 females, 103 males) were included and sinuses were measured in the three axes. Maxillary sinuses measured at birth (mean±standard deviation) 7.3±2.7 mm length (or antero-posterior)/4.0±0.9 mm height (or cranio-caudal)/2.7±0.8 mm width (or transverse). At 16 years old, maxillary sinus measured 38.8±3.5 mm/36.3±6.2 mm/27.5±4.2 mm. Sphenoid sinus pneumatization starts in the third year of life after conversion from red to fatty marrow with mean values of 5.8±1.4 mm/8.0±2.3 mm/5.8±1.0 mm. Pneumatization progresses gradually to reach at 16 years 23.0±4.5 mm/22.6±5.8 mm/12.8±3.1 mm. Frontal sinuses present a wide variation in size and most of the time are not valuable with routine head MRI techniques. They are not aerated before the age of 6 years. Frontal sinuses dimensions at 16 years were 12.8±5.0 mm/21.9±8.4 mm/24.5±13.3 mm. A sinus volume index (SVI) of maxillary and sphenoid sinus was computed using a simplified ellipsoid volume formula, and a table with SVI according to age with percentile variations is proposed for easy clinical application. Percentile curves of maxillary and sphenoid sinuses are presented to provide a basis for objective determination of sinus size and volume during development. These data are applicable to other techniques such as conventional X-ray and CT scan. (orig.)

  1. Preservation of the orbital contents in cancer of the maxillary sinus

    Tumor invasion of the periorbita, posterior ethmoid cells, or orbital apex is considered an absolute indication for orbital exenteration. Preservation of the orbital contents in selected cases can be applied safely to the treatment of primary maxillary sinus cancer. Patient complaints relating to the preserved eye were more commonly associated with radiation therapy than the method of reconstruction used. Reconstruction of the orbital floor with a skin graft, even when combined with radiation therapy, gave a functional eye in the majority of cases while not compromising the oncologic safety or the procedure

    2015-11-01

    The aim of this study was to evaluate the relationship between the maxillary sinus volumes and the nasal septal deviation angles in patients with antrochoanal polyps (ACP). 76 patients who underwent ACP surgery were included in the study. Of those 36 patients who had multislice computed tomography (MSCT) were evaluated to calculate maxillary sinus volume. The records of paranasal MSCT of 36 healthy people without any paranasal sinus diseases or surgery constituted age- and gender-matched healthy controls. Maxillary sinüs volumes and septal deviation angles were calculated using the paranasal MSCT volume-rendering technique. Thirty-six patients in the ACP group were compared with 36 polyp side-matched healthy people. The mean age was 16.6 ± 6.7 years in both groups. Statistically, the mean value of the maxillary sinus volume was significantly higher in the ACP group compared with the ACP side-matched control group (15.1 ± 4.6 versus 12.0 ± 3.5 mm(3)) (p = 0.002). Furthermore, the mean value of the maxillary sinus volume in the non-polyp side (14.2 ± 4.7 mm(3)) was statistically higher in the ACP group compared with the side-matched control group volume (11.9 ± 3.8 mm(3)) (p = 0.024). In addition, Fifty-three of 76 ACP patients had septal deviation. While the septal deviation was on the same side with the ACP in 17 patients, it was on the opposite side in 36 patients. In conclusion, the maxillary sinus volumes increased in ACP patients compared with the healthy control group. Many patients had nasal septal deviation on the opposite side of the ACP. PMID:25534286

  3. A radiologic study on the experimental lesions of the maxillary sinus

    This study was performed to determine the each location of lesions in the maxillary sinus and to evaluate the relationship between the floor of the antrum and the apical regions of teeth by the comparison of the panoramic view and panoramic sinus view. For this study, experimentally with two dry skulls, jelly balls of 8 mm and 15 mm in diameter containing a short wire for the radiopacity similar to the cyst and clinically 5 patients having mucosal cyst in the antrum and 10 patients having periapical lesions of upper molars were formed by using round bur and the radiopaque periapical lesions were simulated by filling the former lesions with lead foil. Each panoramic view and each panoramic sinus view of the experimental lesions and patients were obtained by using panoramic machine and analyzed. The following results obtained; 1. On the panoramic sinus view, the innominate line was approximately coincided with the most lateral portion of the antrum and the posterior wall appeared as the narrow area at the mesial side of the innominate line. The anterior wall occupied totally the mesial side of the innominate line, and the medial wall occupied the mesial half of the antrum. 2. In all cases of experimental cystic lesion attached to each wall of the antrum, the location of each lesion was able to be determined by applying Tube shift technic. 3. The palatal root and mesiobuccal root of the molar appeared as being transposed each other mesiolaterally on the panoramic and panoramic sinus views. 4. The panoramic sinus view was superior to the panoramic view in revealing the relationship between the floor of the antrum and the periapical lesion.

  4. Long term control of a maxillary sinus mucoepidermoid carcinoma with low dose radiation therapy: a case report

    Mucoepidermoid carcinoma of the maxillary sinus is a rare malignancy of the head and neck. The location of this tumour near vital structures and its large size at presentation makes surgical resection with negative margins challenging. In incurable cases, relief from symptoms such as epistaxis may be achieved with radiation therapy. We present a case of mucoepidermoid carcinoma of the maxillary sinus that was effectively palliated with a short course of radiation therapy, achieving complete cessation of bleeding, decrease in tumour size, and long term control. We surveyed the literature on mucoepidermoid carcinomas and propose that some tumours may be particularly radiosensitive, benefiting from even short courses of radiation therapy

  5. Bilateral maxillary sinus floor augmentation with tissue-engineered autologous osteoblasts and demineralized freeze-dried bone

    Aashish Deshmukh

    2015-01-01

    Full Text Available The pneumatization of the maxillary sinus often results in a lack of sufficient alveolar bone for implant placement. In the last decades, maxillary sinus lift has become a very popular procedure with predictable results. Sinus floor augmentation procedures are generally carried out using autologous bone grafts, bone substitutes, or composites of bone and bone substitutes. However, the inherent limitations associated with each of these, have directed the attention of investigators to new technologies like bone tissue engineering. Bone marrow stromal cells have been regarded as multi-potent cells residing in bone marrow. These cells can be harvested from a person, multiplied outside his body using bioengineering principles and technologies and later introduced into a tissue defect. We present a case where tissue-engineered autologous osteoblasts were used along with demineralized freeze-dried bone for sinus floor augmentation.

    Full Text Available Statement of the Problem: Mucous retention cysts (MRCs of the maxillary sinus are lesions with undefined pathogenesis. In recent researches, geographical and climatic aspects have been related as risk factors. Purpose: The purpose of this study was to determine the frequency of MRCs of the maxillary sinus using panoramic radiographs. Materials and Method: A total of 631 panoramic radiographs were selected from a secondary database from a private radiology clinic and analyzed by two specialists in dental radiology according to gender, age, month, relative air humidity, and mean temperature. Results: A total of 87 (6.89% radiographic images were suggestive of MRCs. Thirty-five MRCs (40.22% were detected on the right side, 10 (11.49% on the left side and 42 (48.29% on both sides. A high frequen-cy was detected in female participants (n=45; 51, 72%, those aged 18-35 years (n=31; 35, 63% and those from August (n=24; 27.59% and July (n=22; 25.29%. Conclusion: The frequency of MRCs was low, and no statistically significant correlation was found between the prevalence of MRCs and the studied variables with the exception of the mean temperature.

  8. How far can we exert organ preservation in cancer of the maxillary sinus?

    A combination of radiotherapy, chemotherapy, and surgery improved the 5-year survival rate of patients with cancer of the maxillary sinus by more than 60%. In recent years, considering the QOL of patients when they return to their former social environments, treatment methods exerting organ preservation are expected. The present study evaluated whether the combination of massive intraarterial infusion of CDDP and radiotherapy can reduce the frequency of surgical treatment for cancer of the maxillary sinus. Satisfactory results were obtained after the completion of radiotherapy (regional CR rate: 66.7%, response rate: 91.7%). Moreover, the pathohistological CR rate was 75%, and local control of the cancer was achieved by this combination therapy in 6 of 12 patients (50%) without surgical treatment. Furthermore, the 2-year cumulative survival rate was 75% when evaluated in all patients, using the Kaplan-Meier method. Although the period of investigation was short, the results of the present study suggested that the combination of massive intraarterial infusion of CDDP and radiotherapy could reduce the frequency of surgical treatment and could contribute to organ preservation in cancer therapy.

  9. Retrospective evaluation of surgical intervention following chemo- and radiotherapy of maxillary sinus cancers

    During the past 15 years, 30 patients with squamous cell carcinomas of the maxillary sinus were treated by modified partial maxillectomy following chemo- and radiotherapy, taking care to preserve facial contour and function as far as possible. Follow-up evaluation showed that local recurrences, and regional lymph node and distant metastases were more frequent in T4 patients than in T3 patients. Evaluation of the histopathological effects of preoperative chemo- and radiotherapy at the time of surgery showed that T4 patients tended to have a poorer response to the treatment than T3 patients. Analysis according to the direction of primary tumor extension showed that the incidence of local recurrence was higher in the superolateral type, whereas that of regional lymph node metastasis was higher in the medial type. The cumulative 5-year survival was high (72.2%) in Stage III patients and low (22.5%) in Stage IV patients. The overall rate was 55.4%. The treatment produced relatively good outcomes in T3 patients but poor outcomes in T4 patients. These findings indicate that T4 carcinoma of the maxillary sinus must be managed initially by a combination of irradiation and multi-chemotherapeutic drugs, and then treated by more extensive surgical resection.

    In connection with bilateral maxillary sinus augmentation, the acute effects of the nonsteroidal anti-inflammatory drug carprofen on facial expressions and long-term effects on bone formation were evaluated in 18 male New Zealand White rabbits. A 10×10mm bone window was drilled in the maxilla, the sinus membrane elevated and a titanium mini-implant inserted. One of two test materials was randomly inserted unilaterally and bovine bone chips (control) on the contralateral side in the created space. Rabbits were randomly allocated to receive buprenorphine plus carprofen (n=9) or buprenorphine plus saline (n=9) postoperatively. Buprenorphine was administered subcutaneously every 6h for 3days in a tapered dose (0.05-0.01mg/kg) and carprofen (5mg/kg) or saline administered subcutaneously 1h before, and daily for 4days postoperatively. To assess pain, clinical examination, body weight recording and scoring of facial expressions from photos taken before, and 6-13h after surgery were performed. Twelve weeks after surgery the rabbits were euthanized and sections of maxillary bones and sinuses were analysed with histomorphometry and by qualitative histology. Carprofen had no effect on mean facial expression scores, which increased from 0.0 to 3.6 (carprofen) and 4.3 (saline), of a maximum of 8.0. Neither did carprofen have an effect on bone formation or implant incorporation, whereas the test materials had. In conclusion, treatment with 5mg/kg carprofen once daily for 5days did not reduce facial expression scores after maxillary sinus augmentation in buprenorphine treated rabbits and did not affect long term bone formation.

    Full Text Available Introduction: Comparison of the relationships and distance between maxillary root tips and   the maxillary sinus floor using oral panoramic in the dolichocephalic and brachycephalic compared to mesocephalic individuals. Methods: Oral panoramic images from 300 individuals were analyzed and the relationships and distance between the maxillary root tips and the sinus floor was assessed by qualitative and quantitative variables. Results: The distance was significantly higher in the brachycephalic groups than that of the mesocephalic, and the mesocephalic group showed longer distance in comparison to dolichocephalic individuals. Qualitative comparison showed that type 1 relationship was the dominant position in the brachycephalic individuals while most of dolichocephalic individuals demonstrated type 2 and 3 relationships of the molar root tips and the maxillary sinus floor. Conclusion: Higher distances between the molar root tips and the maxillary sinus floor could be expected in the brachycephalic than mesocephalic and dolichocephalic individuals

    Full Text Available Background. Locally advanced carcinoma of maxillary sinus has been historically reported to have poor prognosis. We evaluated the role of NACT in improving the outcome in these patients. Methods. 41 patients with locally advanced technically unresectable (stage IVa or unresectable maxillary carcinoma (stage IVb were treated with induction chemotherapy between 2008 and 2011. The demographic profile, response and toxicity of chemotherapy, definitive treatment received, progression free survival (PFS, and overall survival (OS were analyzed. Univariate and multivariate analysis were performed to determine factors associated with PFS and OS. Results. The chemotherapy included two drugs (platinum and taxane in 34 patients (82.9% and three drugs (platinum, taxane, and 5 FU in 7 (17.1%. There was no complete response seen in any of the patients, stable disease in 18 (43.9%, partial response in 16 (39%, and progression in 7 (17.1% patients. After induction, the treatment planned included surgery in 12 (29.3%, CT-RT in 24 (58.5%, radical RT in 1 (2.4%, palliative RT in 1 (2.4%, and palliative chemotherapy in 3 (7.3% patients. Overall, the median PFS was 10.0 months. The OS at 24 months and 36 months was 41% and 35%, respectively. Conclusion. In unresectable maxillary carcinoma, induction chemotherapy has clinically significant benefit with acceptable toxicity.

  14. Clinical evaluation of multimodal treatment for squamous cell carcinoma of the maxillary sinus

    Seventy-seven patients with squamous cell carcinoma of the maxillary sinus were treated with radiotherapy and surgery (with or without intra-arterial infusion chemotherapy) from 1969 to 1986 at Tokyo Women's Medical College. The treatment given to the subjects was broadly separated into three categories: Treatment I (1969-1974), Treatment II (1975-1977), and Treatment III (1978-1986). Treatment I consisted of surgery and radiotherapy; Treatment II consisted of multimodal treatment by surgery and radiotherapy with 5-FU intra-arterial infusion chemotherapy (IAIC) from the superficial temporal artery; Treatment III consisted of surgery and radiotherapy with Adriamycin IAIC replacing 5-FU IAIC. Radiotherapy involved a total dose of 60 Gy/6 weeks in Treatment I as the standard, 50 Gy/5 weeks with 5-FU (250 mgx20 times/4 weeks) in Treatment III. Surgery by antrotomy was performed before radiotherapy and IAIC, and Denker's operation was done after radiotherapy with IAIC. The influence of patients' age, sex, T stage and N stage were examined as prognostic factors and no statistically significant differences were seen among each treatment periods. The 2-year control rate was 29% in period I, 27% in period II, and 58% in period III. The 5-year cumulative survival rate was 13% for period I, 40% for period II, and 54% for period III; the incidence of side effects during radiotherapy did not appear to increase, and the severity was at a tolerable level considering the results. However, late complications were seen in 6 cases (cataract, 5; obstinate sinusitis, 1). Thus, the study indicates that multimodal treatment using Adriamycin IAIC can minimize face deformity and allows effective function-saving treatment for carcinoma of the maxillary sinus. (author)

  15. Intra-oral low level laser therapy in chronic maxillary sinusitis: A new and effective recommended technique

    Mortazavi, Hamed; Khalighi, Hamidreza; Goljanian, Ali; Mojahedi, Saeed; Sabour, Siamak

    2015-01-01

    Background Chronic sinusitis is one of the most common chronic diseases involving different age groups. Because the nature and etiology of chronic sinusitis are not completely known, there is not any standard treatment for this disease. It has been suggested that low-level laser can be used in treating chronic sinusitis but there are limited studies about its usage. In this research, intra-oral radiation of low-level laser has been described and implemented for the first time. Suggested hypotheses about the efficacy of this type of radiation (intra-oral) in treating chronic maxillary sinusitis includes this fact that the depth of maxilla’s vestibule is also the floor of maxillary sinus and sinus discharges collect in this area because of gravity effect. Therefore, with considering suitable radiation angle, this area gets the most benefits of laser’s anti-inflammatory effects. Material and Methods In this study, 20 patients with chronic maxillary sinusitis were included. They were assessed before and after treatment. Treatment plan was performed in 8 sessions every other days using low-level diode laser with 810 nm. Snot-22 questionnaire and rhinomanometry were used for evaluating patients. Changes of signs and symptoms were recorded in questionnaire every session and 6 months after treatment. Friedman and Wilcoxon tests were used for data analyses. In this study, P value < 0.05 was considered statistically significant. Results All variables and all symptoms of patients were improved using intra-oral low-level laser and this improvement was statistically significant (P value<0.05). There was also significant decrease in nasal airway resistance and significant increase in air flow (P value<0.05). Six month after treatment completion, there was no significant difference between the results of completion and the results of 8th treatment session (P value< 0.05). Conclusions Using intra-oral low-level laser is a suitable way to treat patients with chronic maxillary

  17. Mesenchymal stem cells in maxillary sinus augmentation: Asystematic review with meta-analysis

    2015-01-01

    AIM To investigate the effectiveness of mesenchymalstem cells (MSCs) in maxillary sinus augmentation(MSA), with various scaffold materials.METHODS: MEDLINE, EMBASE and SCOPUS weresearched using keywords such as sinus graft, MSA,maxillary sinus lift, sinus floor elevation, MSC and cellbased,in different combinations. The searches includedfull text articles written in English, published over a10-year period (2004-2014). Inclusion criteria wereclinical/radiographic and histologic/ histomorphometricstudies in humans and animals, on the use of MSCs inMSA. Meta-analysis was performed only for experimentalstudies (randomized controlled trials and controlledtrials) involving MSA, with an outcome measurement ofhistologic evaluation with histomorphometric analysisreported. Mean and standard deviation values ofnewly formed bone from each study were used, andweighted mean values were assessed to account for thedifference in the number of subjects among the differentstudies. To compare the results between the test andthe control groups, the differences of regenerated bonein mean and 95% confidence intervals were calculated.RESULTS: Thirty-nine studies (18 animal studies and 21human studies) published over a 10-year period (between2004 and 2014) were considered to be eligible forinclusion in the present literature review. These studiesdemonstrated considerable variation with respect tostudy type, study design, follow-up, and results. Metaanalysiswas performed on 9 studies (7 animal studiesand 2 human studies). The weighted mean differenceestimate from a random-effect model was 9.5% (95%CI:3.6%-15.4%), suggesting a positive effect of stem cellson bone regeneration. Heterogeneity was measured bythe I 2 index. The formal test confirmed the presenceof substantial heterogeneity (I 2 = 83%, P 〈 0.0001).In attempt to explain the substantial heterogeneityobserved, we considered a meta-regression model withpublication year, support type

  18. Effect of Schneiderian membrane perforation on sinus lift graft outcome using two different donor sites: a retrospective study of 105 maxillary sinus elevation procedures

    Sakkas, Andreas

    2016-03-01

    Full Text Available Background: Sinuslift is meanwhile an established method of bone augmentation in the posterior maxilla. Aim of the study was to evaluate the significance of intraoperative Schneiderian membrane perforations during maxillary sinus floor elevation surgery using autogenous bone harvested from two different donor sites using a Safescraper device on the success rate, graft survival and implant integration.Methods: The investigators conducted a retrospective cohort study at the Department of Oral and Maxillofacial Surgery of Military Hospital Ulm composed of patients with severe maxillary atrophy who underwent sinus augmentation from January 2011 until December 2011. Ninety-nine consecutive patients (89 men, 10 women with a mean age of 43.1 years underwent sinus graft procedures in a 2-stage procedure using the lateral wall approach, as described by Tatum (1986. Data on patient age, smoking status, donor site and surgical complications were recorded and the relationship between Schneiderian membrane perforation and complication rate was evaluated. Dental implants were inserted 4 months after grafting.Results: A total of 105 sinus lift procedures were performed in 99 patients. Sixty-one patients (61.6% underwent sinus elevation with autogenous bone from the buccal sinus wall, while 38 patients (38.4% bone harvesting from the iliac crest. Intraoperative perforation of the Schneiderian membrane was observed in 11 of the 105 sinuses (10.4%. These perforations resulted in 4 (36.3% of the cases in major postoperative complications accompanied by swelling and wound infection. Membrane perforations were slightly associated with the appearance of postoperative complications (p=0.0762. In 2.4% of all cases, regarding 2 patients the final rehabilitation with dental implants was not possible because of extensive bone resorption. Conclusion: Intraoperative complications performing sinus augmentation may lead to postoperative complications. With careful clinical

  19. Prominent response with helical tomotherapy in recurrent ameloblastic carcinoma of maxillary sinus: a case report

    Ameloblastoma is a benign but locally aggressive tumor of odontogenic epithelial tissue. Reports of radiotherapy treatment modalities are limited in the literature. A thirty-five year old male presented with complaints of headache radiating to his face for about six months and impaired vision. The patient’s Positron Emission Tomography (PET) showed a mass in the left maxillary sinus extending to the nasal cavity and invading the adjacent tissues. An R2 (macroscopic residual tumor) surgical resection performed to debulk the tumor. Due to the recurrence and residual mass, the patient was treated with helical tomotherapy. At 2 months post-radiotherapy, patient’s vision returned to normal. PET scan showed a significant reduction in lesion size 12 months post-radiation. In cases of ameloblastic carcinoma with, post-surgical recurrence or patients not suitable for surgical treatment, helical tomotherapy can be an effective treatment option

  20. Long-term prognosis of maxillary sinus malignant tumor patients treated by fast neutron radiation therapy

    From 1976 through 1990, 19 patients with maxillary sinus malignant tumor were treated with combination therapy consisting of maxillectomy and radiation of fast neutron. Fast neutron radiotherapy was performed at National Institute of Radiological Sciences. Eight patients had adenoid cystic carcinomas, three patients squamous cell carcinomas, one patient a carcinoma in pleomorphic adenoma, four patients fibrosarcomas, one patient osteosarcoma, one patient chondrosarcoma and one patient rhabdomyosarcoma. Fast neutron therapy after/before surgery was effective in fresh cases with T2-3N0M0 adenoid cystic carcinomas and sarcomas (except for fibrosarcoma). Nine patients were alive more than three years after treatment. And serious complications of fast neutron radiation therapy appeared in six of these nine patients. Visual impairment of opposite side occurred in four patients. Bone necrosis occured in one patient and brain dysfunction in one patient. (author)

    The purpose of this study was to retrospectively investigate the efficacy of multidisciplinary therapy (concomitant radiotherapy and intra-arterial infusion of 5-fluorouracil (5-FU) followed by maxillectomy) in the treatment of squamous cell carcinoma of the maxillary sinus. We reviewed 71 patient records with locally advanced but respectable carcinoma of the maxillary sinus treated by means of multidisciplinary therapy between 1978 through 1997. The clinical T factor for these patients, according to the UICC definitions (1997), was 12 for T2, 46 for T3, and 13 for T4. Twelve patients were diagnosed as node-positive at initial presentation. Intra-arterial 5-FU was delivered via a superficial temporal artery in accordance with radiotherapy, and the cumulative 5-FU dose ranged from 2,900 mg to 5,250 mg (median 5,000 mg). The total radiotherapy dose ranged from 29 Gy to 48 Gy (median 48 Gy) with conventional fractionation. Patients underwent radical maxillectomy thereafter. The 5-year overall survival rate and disease-specific survival rate of all the patients were 58% and 68%, respectively. There was no significant correlation of clinical T factor or N factor with disease-specific survival on univariate and multivariate analysis. The overall treatment-related mortality rate was 3.7%. Radiation cataract later developed in all evaluable patients whose lenses were within the treatment volume. About a half of the operable T4 patients survived over 5 years by means of the above-mentioned multidisciplinary therapy. This multidisciplinary therapy should be compared to treatment with a combination of surgery and postoperative chemoradiotherapy. (author)

    2016-01-01

    Purpose. We present a case of a bilateral postoperative maxillary cyst (PMC) and discuss this with a systemic review. Case Report and Literature Review. A 68-year-old female with pain and swelling on the right side of the face. MRI and CT showed a cystic tumors of the right and left maxillary sinus. Radical maxillary surgery via a Caldwell-Luc procedure had been performed 55 years ago and bilateral PMC was diagnosed. The PubMed database was searched for PMC within the last 30 years. Results. Together with the current case, we found 23 reports including 284 patients describing PMC. It was diagnosed at a mean time of 22 years after causal surgery at a mean age of 47 years. Initial symptoms were mostly pain with or without swelling. The main radiological sign was a unilocular radiolucency with a slight preference for the left side. Discussion. PMC is a long-term complication that can occur after maxillary sinus surgery and a second surgical approach is required in order to stop cystic expansion. Therefore, patients' informed consent on this complication as well as a prolonged follow-up is recommended. Simple paranasal ultrasound or paranasal sinus plain radiography may lead to an earlier detection reducing interventional morbidity. PMID:27478654

  5. A 'supralethal dose phenomenon' revealed by cancer of the maxillary sinus

    In this paper a so-called ''supralethal dose phenomenon'' is reported. Two groups of patients, all of whom were carrying proved squamous cell carcinoma of the same clinical stage in their maxillary sinuses, were compared after radiotherapy in our department. The radiotherapies applied to the two groups were very similar in terms of fraction number, treatment period, dose distribution and immobilization technique, but differed in dose, i.e., 5,500 cGy for one group of 9 patients and 5,750 cGy for the other group of 20 patients. The five-year survival rates of the two groups were 8/9 and 10/20, respectively, and the difference was statistically significant (p<0.05). All patients were observed for at least five years. Except for tumor stage, the status of the patients in the two groups, including primary site of the tumor in the sinus, patients' age and cause of death for the failed cases, are also discussed in detail.

    Aim To evaluate the effects of maxillary sinus floor elevation by a tissue-engineered bone complex of β-tricalcium phosphate (β-TCP) and autologous osteoblasts in dogs. Methodology Autologous osteoblasts from adult Beagle dogs were cultured in vitro. They were further combined with β-TCP to construct the tissue-engineered bone complex. 12 cases of maxillary sinus floor elevation surgery were made bilaterally in 6 animals and randomly repaired with the following 3 groups of materials: Group A (osteoblasts/β-TCP); Group B (β-TCP); Group C (autogenous bone) (n-4 per group). A polychrome sequential fluorescent labeling was performed post-operatively and the animals were sacrificed 24 weeks after operation for histological observation.Results Our results showed that autologous osteoblasts were successfully expanded and the osteoblastic phenoltypes were confirmed by ALP and Alizarin red staining. The cells could attach and proliferate well on the surface of the β-TCP scaffold. The fluorescent and histological observation showed that the tissue-engineered bone complex had an earlier mineralization and more bone formation inside the scaffold than β-TCP along or even autologous bone. It had also maximally maintained the elevated sinus height than both control groups. Conclusion Porous β-TCP has served as a good scaffold for autologous osteoblasts seeding. The tissue-engineered bone complex with β-TCP and autologous osteoblasts might be a better alternative to autologous bone for the clinical edentulous maxillary sinus augmentation.

  7. Evaluation of Anatomic Variations in Maxillary Sinus with the Aid of Cone Beam Computed Tomography (CBCT in a Population in South of Iran

    Full Text Available Statement of the Problem: Anatomic variations of the maxillary sinus can be detected in cone-beam computed tomography (CBCT and may assist to locate the posterior superior alveolar artery (PSAA and define the maxillary sinus morphology more accurately for a more strict surgical treatment plan. Purpose: The study aimed to determine normal variations of the maxillary sinus with the aid of CBCT in a sample population in south of Iran. Materials and Method: This cross-sectional prevalence study was based on evaluation of 198 projection data of CBCT scans of some Iranian patients aged 18-45, referred to a private oral and maxillofacial radiology center in Shiraz from 2011 to 2013. CBCT scans were taken and analyzed with NewTom VGi device and software. The anatomic variations which were evaluated in the axial images included the presence of alveolar pneumatization, anterior pneumatization, exostosis, and hypoplasia. Moreover, the location and height of sinus septa and the location of PSAA were assessed. SPSS software (version 17.0 was used to analyze the data. Results: In a total of 396 examined sinuses, maxillary sinus alveolar pneumatization was the most common anatomic variation detected. Anterior pneumatization was detected in 96 sinuses (24.2%. Antral septa were found in 180 sinuses (45.4% and were mostly located in the anterior region. Meanwhile, PSAA was mostly detected intra-osseous in 242 sinuses (65.7%. Conclusion: Anatomic variations of the maxillary sinus were common findings in CBCT of the maxilla. Preoperative imaging with CBCT seems to be very helpful for assessing the location of PSAA and the maxillary sinus morphology; Its data might be used to adjust the surgical treatment plan to yield more successful treatments.

    The unicystic ameloblastoma (UA) presents the clinical and radiographic characteristics of a maxillary cyst, making early diagnosis difficult. A 30-year-old man had an extensive, asymptomatic lesion in the right maxillary sinus. Radiographic examinations demonstrated a retained tooth in association with a lesion. Histopathologic examination revealed the presence of UA with intraluminal and mural infiltration and a follicular pattern. Le Fort I access was chosen for enucleation of the lesion and curettage of the site, which were followed by cryotherapy. The treatment provided adequate intraoperative visibility, enabled the preservation of the surrounding bone, and eliminated postoperative complications. Follow-up over 5 years demonstrated no recurrence. PMID:27148651

    Monje, Alberto; Monje-Gil, Florencio; Burgueño, Miguel; Gonzalez-Garcia, Raúl; Galindo-Moreno, Pablo; Wang, Hom-Lay

    2016-01-01

    Maxillary sinus membrane perforation has been reported as the most common intraoperative complication during sinus augmentation, potentially leading to postoperative infection and consequent loss of graft or even implant failure. Numerous anatomical factors have been demonstrated to affect membrane tearing. However, careful use of proper instrumentation, such as a reamer, seems to play an important role in minimizing the incidence of these complications. Hence, the aim of the present study was to (1) investigate the reliability of reamer drilling for lateral window preparation; (2) examine the incidence of membrane perforation; and (3) study the factors that might influence membrane perforation. Results from this study showed the safety and effectiveness of using a reamer to perform lateral window approach sinus augmentation. The sinus membrane perforation rate was found to be 12.5%. A slightly higher perforation rate was noted in thinner maxillary lateral walls (< 1.25 mm). The authors concluded that reamer drilling is a safe and effective alternate technique for opening the lateral window wall when the lateral wall thickness is ≥ 1.25mm. PMID:27333013
